Whether you keep a backyard flock of chickens, a few horses on a larger lot, goats, rabbits, or simply want to support local wildlife through the seasons, feed quality and consistency matter more than most property owners realize.
In New Jersey, where temperatures swing from humid summers to hard winters, animals depend on their owners to adjust nutrition accordingly. To source feed that is fresh, properly stored, and matched to their specific needs.
This guide covers the basics for Princeton-area property owners: what to feed, why freshness matters, how to store feed correctly, and how to avoid the most common mistakes.
Choose Feed Based on Animal Type
Not all animals thrive on the same nutrition, and using the wrong feed, even a high-quality one, can cause real problems over time. Here is a practical overview of what each type of animal needs.
Horse Feed
Horses are hindgut fermenters, meaning forage, such as hay or pasture grass, should always make up the foundation of their diet. Grain and concentrated feeds supplement that base when horses have higher energy demands: growing youngsters, hard-working horses, lactating mares, or animals that struggle to hold weight on forage alone.
Look for feeds with appropriate protein levels for your horse’s life stage. Adult horses in light work typically do well on 10 to 12 percent protein, while young horses and lactating mares need more. Avoid sudden feed changes, which can disrupt gut health and increase colic risk. Any transition to a new feed should happen gradually over 7 to 10 days.
Chicken & Poultry Feed
Layer hens need feed specifically formulated with calcium to support strong eggshell production, typically around 16 percent protein and 3.5 to 4.5 percent calcium. Chicks and pullets, on the other hand, need starter or grower formulas with higher protein and no added calcium, which can damage developing kidneys.
Meat birds like Cornish Cross have different needs still, requiring high-protein broiler feed to support their rapid growth. If your flock is mixed, pay attention to life stage and purpose rather than using a single feed for everyone.
Goat & Sheep Feed
Goats and sheep are both small ruminants, but they have meaningfully different nutritional requirements. Sheep are sensitive to copper, and feeding them goat feed can lead to copper toxicity over time. Always use species-specific feed.
Both animals need good-quality forage as their primary diet. Grain supplements support late pregnancy and lactation, growing kids, or animals in poor condition. Avoid overfeeding grain, which is a common mistake that leads to digestive problems including enterotoxemia.
Rabbit Feed
Rabbits do well on a diet anchored by high-quality grass hay. Pellets should be a supplement, not the primary food source. Fresh vegetables and leafy greens can round out the diet, but fruits and high-sugar foods should be offered sparingly.
Choose pellets with at least 18 percent fiber and around 14 to 16 percent protein for adult rabbits. Pellets with seeds, nuts, or colorful pieces added in look appealing to buyers but offer little nutritional value and can cause rabbits to pick out the less healthy elements and leave the rest.
Wildlife Feed
Supporting local wildlife on your Princeton property is rewarding, but it requires some thought about what you are putting out and when. Black oil sunflower seed attracts the widest variety of wild birds and is a reliable year-round option. Nyjer seed (also called thistle) brings in finches. Suet is especially valuable in winter when birds need high-fat food to maintain body temperature.
Avoid general-purpose mixes with a lot of filler grain like milo or red millet, which most desirable birds will ignore. And be mindful of what your feeders might attract beyond birds: unsecured feed can draw rodents and deer, which causes its own problems.
Why Fresh Feed Matters for Animal Health
Feed freshness is one of the most underappreciated factors in animal care, and it is one of the areas where local sourcing makes a genuine difference.
Commercial feed begins losing nutritional value as soon as it is manufactured. Vitamins, particularly fat-soluble ones like A, D, and E, degrade over time, especially when feed is exposed to heat, humidity, or light. Feed that has been sitting in a warehouse or on a store shelf for months may look and smell fine but deliver significantly less nutrition than the label suggests.
Mold is a more immediate concern. Mycotoxins produced by mold can sicken animals even when the mold itself is not visible to the naked eye. Horses are particularly sensitive to moldy hay and grain. Poultry and rabbits are also vulnerable. Feed that has been improperly stored at any point in the supply chain, whether at the manufacturer, distributor, or retailer, carries elevated risk.
Locally milled feed offers real advantages here. Shorter time between milling and purchase means vitamins are more intact, mold risk is lower, and you are more likely to know where your feed came from and how it was handled. For Princeton-area property owners, sourcing from a local feed supplier rather than a big-box retailer is a meaningful difference, not a marketing distinction.
Freshness also affects palatability. Animals will often refuse or under-eat stale feed, which throws off your sense of how much they are actually consuming and can mask early health issues.
Adjust Feeding During Seasonal Changes
New Jersey’s climate puts real demands on animals in every season, and their nutritional needs shift accordingly.
Winter is when most property owners need to increase feed. Animals burn significantly more calories maintaining body temperature in cold weather, especially those kept outdoors or in unheated structures. Horses in particular may need more hay during cold snaps — hay fermentation in the hindgut generates heat and helps horses stay warm from the inside. Fresh, clean water is critical in winter too. Horses and livestock will reduce water intake if water is too cold, which raises the risk of impaction colic and urinary problems. Heated water buckets or tank heaters are worthwhile investments in central New Jersey winters.
Spring brings the challenge of pasture transition. When horses and livestock go from dry lot or hay-only diets to fresh spring grass, the shift needs to be gradual. New growth grass is high in sugars and can trigger digestive upset, laminitis in horses, or bloat in goats and sheep. Limit access to pasture in the early weeks of spring and increase turnout time slowly over two to three weeks.
Summer heat suppresses appetite in many animals. Monitor feed consumption carefully and make sure water is always fresh and cool. Heat also accelerates feed spoilage — bags left in hot storage areas or outdoor bins can go bad faster than expected.
Fall is a good time to reassess body condition before winter sets in. Animals heading into cold weather underweight will struggle. Fall is also when pasture quality declines and hay should become the primary forage source again. Stock up before winter demand drives prices up.
Store Animal Feed Properly
Proper storage protects your investment, protects your animals, and extends the useful life of your feed.
Keep feed dry. Moisture is the primary enemy. Even slightly damp feed can develop mold within days. Store bags off the ground on pallets or shelves, away from walls where condensation can form. In humid New Jersey summers, a dehumidifier in your feed room is worth considering.
Use sealed containers. Galvanized metal bins with tight-fitting lids are the standard recommendation for good reason. They keep out rodents and insects, reduce moisture exposure, and are durable. Plastic bins can work but degrade faster and are easier for rodents to chew through. Whatever you use, clean bins out completely before adding new feed — old feed residue at the bottom is a source of mold and bacterial contamination.
Keep feed out of the sun. UV light and heat both degrade vitamins and accelerate spoilage. An interior feed room is better than an outdoor shed, and a shaded shed is better than one that bakes in afternoon sun.
Follow rotation. Use older feed before opening new bags. This sounds obvious but is easy to skip when you are refilling bins quickly. Letting old feed sit at the bottom while you pile new feed on top is one of the most common causes of gradual, hard-to-trace nutritional decline in animals.
Know your shelf life. Most pelleted and extruded feeds have a shelf life of 3 to 6 months from the manufacture date when stored correctly. Hay quality declines over time as well, though properly cured and stored hay can last through a full season. When in doubt, check for off smells, visible mold, unusual dust, or reluctance from animals to eat it.
Bulk vs Bagged Feed: Which Is Right for Your Property?
The right choice depends on how many animals you have, how much storage space you have, and how quickly you go through feed.
Bagged feed is the right choice for most backyard owners; a few chickens, a rabbit or two, or a single horse getting a small grain supplement. Bags are easy to manage, let you try different products without committing to large quantities, and keep feed fresh as long as you are cycling through bags regularly. The downside is cost per pound, which is higher than bulk, and the inconvenience of frequent trips to restock.
Bulk feed makes sense when you have multiple animals, high feed volume, and adequate storage. The price per pound is lower, delivery eliminates regular supply runs, and you reduce packaging waste. The tradeoff is that you need proper storage infrastructure: clean, sealed bins large enough to hold the delivery, in a space that is protected from heat and moisture. If your storage is inadequate, bulk purchasing can actually lead to more waste and spoilage than buying bagged feed in smaller quantities.
For hobby farms around Princeton, bulk delivery is often the right call once your setup can support it. For single-animal or very small operations, bagged feed remains practical and flexible.
Common Animal Feeding Mistakes
- Feeding the wrong protein levels. Too much protein is wasteful and can stress kidneys over time. Too little leads to poor growth, coat condition, and immune function. Match your feed to the animal’s life stage, workload, and species. A laying hen and a meat chick have very different needs, as do a retired trail horse and a horse in active competition.
- Poor storage. Feed left in open bags, plastic grocery sacks, or outdoor bins without sealing is an invitation to rodents, insects, and mold. Invest in proper containers before you invest in premium feed — it is a waste of money to buy quality feed and then store it carelessly.
- Inconsistent feeding schedules. Animals, especially horses and poultry, thrive on routine. Irregular feeding times cause stress, disrupt digestive rhythms, and in horses can contribute to gastric ulcers. Feed at the same times each day as much as possible.
- Overfeeding treats and scraps. Kitchen scraps, bread, and high-sugar treats seem harmless but can cause real problems. In horses, too many sugary treats can contribute to metabolic issues. In chickens, excess scraps displace balanced nutrition and can affect laying. In goats, certain kitchen scraps are outright toxic. Treats should be a small, occasional addition — not a daily supplement.
- Ignoring seasonal nutrition changes. Many property owners set up a feeding routine in fall and run it unchanged through spring. As discussed above, an animal’s caloric needs change significantly across seasons, pasture quality varies, and some supplements become more or less necessary depending on what the animal has access to. Revisit your feeding program at least twice a year.
FAQ
What type of feed is best for backyard chickens?
For laying hens, a complete layer feed with around 16 percent protein and 3.5 to 4.5 percent calcium is the standard recommendation. Look for a feed without excessive filler grain. Supplemental oyster shell, offered separately, lets hens self-regulate their calcium intake. Chicks need starter feed until around 6 weeks, then grower feed until they begin laying at 16 to 20 weeks of age.
How often should animal feed be replaced?
Most pellet and mixed feeds should be used within 3 to 6 months of the manufacture date. Hay used within the season it was cut is generally best. The practical rule is: if your animals are reluctant to eat it, or if you notice smells, visible mold, or excessive dust, replace it. Regularly cleaning your storage bins also prevents old residue from contaminating new feed.
Does fresh feed make a difference?
Yes, noticeably so. Feed loses nutritional value over time, particularly vitamins A, D, and E. Locally sourced or locally milled feed that moves quickly from production to purchase retains more of its nutritional value than feed that has spent weeks or months in a distribution chain. Animals on fresher feed often show better coat condition, energy levels, and feed intake compared to those eating older stock.
What is the best way to store animal feed?
In sealed, galvanized metal bins kept in a cool, dry, shaded space off the ground. Clean bins out completely before adding new feed. In summer, a fan or dehumidifier in your feed room reduces moisture and slows heat buildup. Always use older feed before opening new bags.
Can bulk feed be delivered near Princeton?
Yes. Belle Mead Co-Op offers bulk and bagged feed delivery to Princeton and the surrounding Mercer County area. If you are going through significant quantities of feed, delivery is often more economical and convenient than repeated store runs.
Note: bulk feed delivered in totes (which can weigh up to 2,000 lbs) requires the customer to have equipment on-site, such as a forklift, to unload the truck, since our delivery vehicles aren’t equipped to unload them. Bagged feed doesn’t have this requirement.
What feed works best for horses during winter?
Quality grass hay should be the cornerstone of a horse’s winter diet. Horses generate body heat through hay digestion, so increasing hay during cold spells is one of the most effective ways to help them stay warm. If a horse is losing weight or has higher energy demands, a concentrated senior feed or a fat supplement can help. Fresh, unfrozen water access is just as important as feed because horses that do not drink enough in winter are at elevated colic risk.
Getting your feed from a knowledgeable local source makes a real difference, especially when your animals’ needs change with the seasons or you have questions that a big-box store employee simply cannot answer.
Belle Mead Co-Op has served Princeton-area property owners for generations, carrying fresh and locally milled feed, trusted national brands, and a full range of supplies for horses, poultry, goats, rabbits, and backyard wildlife. Whether you need a single bag of layer pellets or bulk delivery to a working farm, the team can help you figure out what your animals actually need and get it to you without the runaround.
Stop in or call ahead to talk through your feeding program. Good feed, properly sourced and stored, is one of the most straightforward things you can do for the health of the animals in your care.
