Guinea fowl need more calories, consistent access to protein-rich feed, and supplemental greens to stay healthy through winter. During warm months, these birds get up to half their diet from foraging on insects, seeds, and vegetation. Once snow covers the ground and bugs disappear, you need to make up the difference with a well-rounded feeding plan.
Base Feed and How Much More They’ll Eat
A 16% protein layer mash or crumble serves as the foundation of a guinea fowl’s winter diet. Keep feeders full so birds can eat freely throughout the day. Expect your flock’s total feed intake to increase by as much as 25% during cold weather, since their bodies burn significantly more energy just maintaining core temperature. If you normally go through a 50-pound bag of feed in a certain timeframe, plan to restock sooner.
Pellets and crumbles are the most efficient base feeds because birds waste less compared to loose mash. Store feed in sealed bins to prevent moisture and rodent access, both of which become bigger problems in winter when wild animals are also looking for easy calories.
Cracked Corn and Scratch Grains for Warmth
Cracked corn is one of the best cold-weather supplements you can offer guinea fowl. It’s high in carbohydrates, and digesting those carbs generates lasting metabolic heat that helps birds stay warm. The ideal time to feed cracked corn or a scratch grain mix is in the evening, roughly 30 to 60 minutes before your flock roosts for the night. This gives them a full crop of slow-digesting grain that fuels heat production through the coldest hours.
Scratch grains shouldn’t replace the base layer feed. Think of them as a calorie-dense evening snack. A handful per bird at bedtime is a reasonable starting point. If you notice birds looking thin or fluffed up and lethargic in the morning, increase the amount slightly.
High-Protein Supplements
Guinea fowl are naturally heavy insect eaters, consuming ticks, beetles, and larvae all summer. Winter strips away that protein source, so supplementing makes a noticeable difference in feather condition, body weight, and overall vitality.
Mealworms are an excellent option. They’re the larvae of darkling beetles and provide protein, calcium, and vitamins. You can buy them dried in bulk or raise them yourself. Dried mealworms are easier to store and won’t spoil, making them practical for daily winter use. Scatter a few tablespoons per bird a few times a week, or offer them in a shallow dish.
Black soldier fly larvae are another high-protein, high-fat option that guinea fowl readily eat. Suet, the hard fat from beef, is also valuable in cold weather because animal fat is calorie-dense and easily metabolized by birds. You can hang suet cakes (the kind sold for wild birds, ideally mixed with seeds or dried insects) in the coop or run. Raw suet spoils quickly above freezing temperatures, so it’s actually best suited to winter feeding. Once temperatures start climbing in spring, switch to rendered suet cakes or stop offering it altogether.
Replacing Foraged Greens
When the ground is frozen or snow-covered, guinea fowl lose access to the grasses, weeds, and leafy plants they normally graze on. You can fill this gap with a variety of vegetables and dried forage.
Alfalfa hay is one of the most popular winter greens substitutes among poultry keepers. A small bale from a feed store will last a modest flock for weeks. You can toss a flake into the run for birds to scratch through, which also gives them something to do during the long indoor hours. Dried alfalfa cubes (sold in the rabbit and small animal section of pet stores) work too. Some keepers soak or ferment these cubes with the regular feed to soften them.
Fresh vegetables guinea fowl typically enjoy include cabbage, broccoli, kale, Swiss chard, turnip greens, peas, sweet potato, and acorn squash. Hanging a whole cabbage from a string in the coop gives birds a slow-release source of greens and keeps them entertained. Cucumber, peppers (including the seeds), and thawed frozen mixed vegetables all work as occasional treats. Avoid avocado, raw dried beans, and anything moldy.
Grit and Calcium in Winter
Free-ranging guinea fowl normally pick up small stones and coarse sand from the ground, which sit in the gizzard and grind food. In winter, snow and frozen ground make natural grit nearly impossible to find. If your birds eat whole grains, scratch, greens, or any food beyond processed pellets, they need supplemental grit. Crushed granite, sold as “poultry grit” at feed stores, is the standard choice. Offer it free-choice in a small dish so birds can take what they need.
If your guinea hens are laying, provide crushed oyster shell alongside the grit (in a separate container). Oyster shell dissolves slowly in the digestive system and supplies calcium for strong eggshells. Layer feed contains some calcium, but free-choice oyster shell lets each bird top up based on her own needs. Birds that aren’t laying will generally ignore it.
Keeping Water From Freezing
Water is just as critical as feed in winter, and frozen waterers are the most common daily headache for cold-climate flock owners. Dehydrated birds eat less, lose weight, and stop laying.
If your coop has electricity, a heated poultry waterer is the simplest solution. These units keep water just above freezing without running up a significant electric bill. Heated base plates that sit under a standard metal waterer are another option. For a budget approach, a submersible bucket heater dropped into a five-gallon waterer works well.
Without electricity, you have a few strategies. Black rubber tubs absorb sunlight and slow freezing better than metal or plastic containers. Placing a sealed bottle of salt water inside the waterer acts as a thermal battery, since salt water freezes at a lower temperature and keeps the surrounding fresh water liquid longer. You can also simply bring out fresh lukewarm water two or three times a day, swapping out frozen containers each time. Even with heated systems, check waterers at least once daily to make sure everything is functioning and the water is clean.
A Simple Daily Winter Feeding Schedule
- Morning: Fill feeders with 16% protein layer feed. Refresh water (or check heated waterers). Offer a handful of mealworms or other protein supplement.
- Midday: Toss in fresh greens, a cabbage, or a flake of alfalfa hay. Check water again if using a manual system.
- Evening (before roost): Scatter cracked corn or scratch grains. Top off water one last time.
Keep crushed granite grit and oyster shell available at all times in separate dishes. Adjust total feed amounts upward if birds seem to be losing weight or if temperatures drop sharply. Guinea fowl are hardy birds, but a reliable winter feeding routine is what carries them through to spring in good condition.
