Goslings are hardy, fast-growing birds, but they need consistent warmth, the right nutrition, and protection from predators during their first few weeks of life. Most goslings can transition to outdoor pasture by five or six weeks if the weather cooperates. Getting them there healthy takes attention to a few key details: temperature, feed protein levels, niacin supplementation, and safe housing.
Setting Up the Brooder
Before your goslings arrive, you need a brooder: a warm, draft-free enclosure with a heat source, clean bedding, and room to move. A large plastic tub works for the first few days, but goslings grow fast, so plan on transitioning to a bigger pen within the first week or two. Allow one to two square feet of floor space per bird. That range accounts for growth; start toward the lower end and expand as they get bigger.
Start the brooder at about 90°F at the edge of the heat source. Reduce the temperature by 5 to 10 degrees each week until you reach 70°F. Watch the goslings themselves for the best feedback: if they’re huddled directly under the heat lamp, they’re too cold. If they’re pressed against the walls away from it, they’re too warm. Evenly spread, active goslings mean the temperature is right.
A heat lamp with a red or ceramic bulb is the most common heat source. Secure it firmly so it can’t fall into the bedding. Heat plates designed for poultry are a safer alternative and reduce fire risk significantly.
Choosing Safe Bedding
Pine shavings are the standard choice for gosling bedding. They absorb moisture well, produce relatively low dust, and are associated with fewer foot problems compared to straw. Avoid cedar shavings, which contain aromatic oils that irritate the respiratory tract. Fine sawdust and peat moss generate more dust than pine shavings and can cause breathing issues, especially in young birds whose airways are still developing.
One serious concern with any wood-based bedding is fungal contamination. Aspergillus, a mold commonly found in damp or improperly stored wood shavings, causes severe respiratory disease in young poultry. It can kill goslings quickly. Buy bedding from a reliable source, keep it dry before use, and change it frequently. Goslings produce a lot of moisture from droppings and water spills, so expect to top off or replace bedding every day or two.
For the first day or two, some raisers cover the bedding with paper towels or shelf liner to prevent goslings from eating shavings before they learn what food is. Slippery surfaces like newspaper can cause leg problems, so avoid them or cover them with something textured.
Feeding Goslings the Right Diet
Goslings do well on a waterfowl starter feed with around 15 to 18% protein for the first four weeks. Unlike chicks, goslings don’t need extremely high-protein feeds, and too much protein can actually cause problems (more on that below). If you can’t find waterfowl-specific feed, an unmedicated chick starter in that protein range works, but you’ll need to add niacin.
Niacin (vitamin B3) is critical for goslings. Chick feeds are typically formulated for chickens, which need less niacin than waterfowl. Without enough niacin, goslings develop bowed legs and a condition called perosis, where the tendons slip out of place at the joint. Research has shown that adding 30 to 40 mg of niacin per kilogram of feed completely prevents these leg deformities. The simplest approach for a small flock is to add brewer’s yeast to the feed at roughly 1 tablespoon per cup of feed, or dissolve niacin tablets in the water. Look for plain niacin, not the “no-flush” form, which is less effective.
After four weeks, you can gradually transition to a lower-protein grower feed (around 15%) and begin offering more forage. Goslings are natural grazers and will eat grass enthusiastically once they have access to it. Fresh greens like chopped lettuce or grass clippings can be introduced within the first week as a supplement, not a replacement for their main feed.
Always provide fresh, clean water deep enough for goslings to dip their whole bill in. They need to wash food from their nostrils as they eat. A shallow dish or poultry waterer works, but make sure it’s not deep enough for them to climb into and get chilled. Drowning in water dishes is a real risk in the first two weeks.
Preventing Angel Wing
Angel wing is a deformity where the last joint of the wing twists outward, causing the flight feathers to stick away from the body instead of lying flat. It develops during the rapid growth phase, typically between three and eight weeks of age, and it’s primarily a nutritional problem. The main causes are overfeeding, excessive protein, and deficiencies in calcium, manganese, or vitamin D.
Cases are visually graded from slight (feathers angling less than 30° from the body) to severe (more than 60°). Caught early, angel wing can sometimes be corrected by taping or wrapping the wing against the body for a few days while adjusting the diet. Severe cases are permanent.
The best prevention is straightforward: don’t overfeed high-protein diets, provide access to grass and forage once goslings are old enough, and make sure their feed includes adequate minerals. This is one reason waterfowl-specific feeds exist. They balance protein and minerals for birds that grow rapidly but don’t tolerate excess protein the way meat chickens do.
Moving Goslings Outdoors
Goslings can begin spending time outside during warm, dry days as early as two to three weeks old, as long as temperatures are mild and you bring them back to the brooder afterward. By five to six weeks, most goslings are feathered enough to handle outdoor temperatures down to about 50°F without supplemental heat. The exact timing depends on your climate, the breed, and how quickly they feather out.
Start with short supervised outings on sunny days. Goslings need protection from rain and wind until they have enough feathering to shed water. Wet, chilled goslings can die from hypothermia surprisingly fast. Once they’re fully feathered and nighttime temperatures stay above 50°F, they can move to outdoor housing permanently.
Geese are excellent foragers. A good pasture with short, tender grass can supply a significant portion of their diet once they’re old enough to graze. This reduces feed costs and produces healthier birds. Rotate grazing areas when possible to prevent parasite buildup and keep the grass in good condition.
Predator-Proof Housing
Goslings are vulnerable to raccoons, weasels, foxes, hawks, snakes, and rats. Adult geese can fend off some threats, but young goslings are defenseless. Their enclosure needs to be secure at night and during any unsupervised time.
Hardware cloth is the gold standard for predator-proofing. Use 1/4-inch mesh to keep out even small predators like weasels and snakes. Go with 19-gauge wire or thicker for durability. Standard chicken wire has openings large enough for raccoons to reach through and weasels to slip through entirely, so it’s not adequate on its own.
Cover the top of any outdoor run. Hawks and owls will take goslings in broad daylight. Bury hardware cloth or extend it in an L-shape at least 12 inches outward along the ground around the perimeter to prevent digging predators from tunneling in. Make sure doors and latches are raccoon-proof: raccoons can open simple hook-and-eye latches and twist knobs.
For the nighttime shelter, a simple three-sided shed or enclosed coop works well. Geese don’t roost on bars like chickens, so they need floor space rather than perches. Keep the floor bedded with straw or shavings, and ensure good ventilation near the roofline to prevent moisture buildup without creating drafts at ground level.
Water for Swimming
Goslings love water, but they shouldn’t have access to deep swimming water until they’re at least two weeks old and supervised. Their down isn’t waterproof the way adult feathers are. In the wild, the mother goose’s oil gland transfers waterproofing to her goslings through contact. Brooder-raised goslings don’t get that benefit and can become waterlogged and chilled quickly.
Start with a shallow pan they can splash in, and let them swim for short periods in lukewarm water while you watch. After swimming, return them to the warm brooder to dry off. By four to five weeks, as their feathers come in and they begin producing their own waterproofing oil, they can handle longer water access. By six weeks, most goslings manage water confidently on their own.
