Raising goslings is easier than raising chicks in most respects and harder in two specific ones. They are hardy, they feather fast, they forage almost immediately, and they are far less prone to the mystery deaths that thin a batch of chicks. But they need more niacin than chick feed supplies, and they grow fast enough that a slightly too-rich diet permanently deforms their wings. Get those two right and the rest is straightforward. Get them wrong and you end up with sound-looking birds that cannot walk properly or fly at all.
Key Takeaways
Setting Up the Brooder Before They Arrive
Goslings need more room than chicks and they need it sooner. Start at about 1 square foot per bird and expect to double that by week three and double it again by week five. A brooder that looks generous on day one is crowded by the end of the fortnight, and crowding is what turns minor problems into outbreaks.
Use a heat plate or a lamp at one end rather than heating the whole space, so the birds can choose. Start at 90 degrees F under the heat and drop roughly 5 degrees a week, reaching ambient by week six. The thermometer is a guide, not the answer. Goslings piled directly under the heat are cold; goslings pressed against the far walls are too hot; goslings scattered and dozing across the whole floor have it about right.
Bedding is where waterfowl differ most from chicks. Goslings are wet birds. They splash, they have loose droppings, and they will soak bedding faster than you expect. Use pine shavings or chopped straw, never cedar, and plan on changing it daily rather than weekly. Damp bedding is the direct cause of most chilling and respiratory trouble in young waterfowl. You may need to change it daily.
- Avoid slippery surfaces. Newspaper or bare plastic causes splayed legs. Use shavings or a rubber shelf liner.
- Use a shallow water trough the birds can climb out of. Goslings drown with depressing ease.
- Put the water at the cool end, away from the bedding you want to keep dry.
- Cover the brooder. Goslings jump and flap earlier than people expect.
Feeding: Niacin Is the Whole Ballgame
This is the part that catches people out, so it is worth being blunt about. Waterfowl need roughly twice as much niacin as chickens, and standard chick starter is formulated for chickens. A gosling raised on it develops bowed, weak legs somewhere around week two or three, becomes reluctant to stand, and by the time the problem is obvious the damage is largely done.
The fix is simple and cheap. Use an unmedicated waterfowl or all-flock starter at 20 to 22 percent protein. If you genuinely cannot source one, supplement chick starter with brewer yeast at roughly one tablespoon per cup of feed, or add niacin to the drinking water. Do not skip this because the goslings look fine in week one. They always look fine in week one.
Avoid medicated chick starter entirely. The coccidiostat is dosed for a chick eating a chick quantity, and a gosling eats considerably more by body weight, which can take it into harmful territory. Step down to a 15 to 16 percent grower at around three weeks, because staying on high protein too long is what drives the wing problem below.
Grass matters from the beginning. Goslings can graze within days and should have access to short tender grass from the first week, weather permitting. It does as much for gut development as any bagged feed, and it starts them on the diet they will live on as adults, which our seasonal guide to what geese eat covers in full.
Angel Wing and How to Stop It
Angel wing is a permanent outward twist of the wing tip, and it is a nutrition problem rather than an injury. The flight feathers grow faster than the wing structure can support, the weight pulls the joint outward, and once the bone sets in that position it stays there. The bird cannot fly and, on show birds, is disqualified. On a homestead it is mostly cosmetic, but it is entirely avoidable and worth avoiding.
The cause is too much protein and energy too fast. Check the wings every few days from week three onward. A healthy wing lies flat against the body. If you see the tip starting to lift or rotate away, cut the protein immediately, get the bird off any high-energy treats, and increase grazing time. Caught in the first few days there is a real window in which it corrects. Some keepers also wrap the wing against the body with vet tape for a few days, which can help if the diet is fixed at the same time.
Bread and scratch grains are the usual culprits on small properties, offered kindly and doing exactly the wrong thing.
Raising Goslings Week by Week
Weeks 1 to 2
Heat at 90 degrees F dropping to 85. Unmedicated starter at 20 to 22 percent, free choice, with niacin covered. Shallow water at all times. Short supervised grass time on warm days. Handle them daily, briefly and calmly, because temperament is largely set in this window and it costs you nothing now to save yourself an aggressive gander later. Our guide to raising friendly geese covers that groundwork properly.
Weeks 3 to 4
Heat down to 80 then 75 degrees F. Step to a 15 to 16 percent grower. Space needs are climbing fast now and this is the point most brooders become too small. Start checking wings. Supervised swims of five to ten minutes on warm days only, drying the birds afterwards, because they are still not waterproof.
Weeks 5 to 6
Heat down to 70 degrees F then off entirely if nights allow. Feathers replace down across the body. Begin moving them outside during the day into a secure run, bringing them in at night. Grazing should now be a real part of the diet rather than an outing.
Weeks 7 to 8
Fully outdoors provided nights stay above about 50 degrees F. Grain intake drops as grass takes over. Weigh weekly if you can and separate any bird more than 2 pounds under the batch average, because a gosling falling behind at this stage is usually being outcompeted at the feeder rather than being ill. By the end of week eight you are essentially keeping small geese.
Predators, Water, and the Two Ways Goslings Die
Almost every gosling loss on a small property comes down to one of two things: drowning or predation. Both are preventable and neither is subtle.
Drowning happens in water containers with sides the bird cannot climb, and in unsupervised deep water before the feathers come in. Goslings lack the preen oil adults use to stay waterproof and buoyant, so they waterlog, chill, and go under. Use shallow troughs with a ramp or stones, and keep swims short and watched until week six.
Predation is worse because it takes the whole batch rather than one bird. Goslings are the easiest target on the property and rats, hawks, raccoons, and neighbourhood dogs will all take them. Roof the run, secure the brooder at night, and do not assume a fence that holds adult geese holds a gosling. The cooperative extension system has a solid practical overview of raising geese in small or backyard flocks that covers housing requirements in more detail.
Introducing Goslings to an Established Flock
Do not put goslings straight in with adult geese. Wait until they are close to full size, which realistically means 10 to 12 weeks, and even then introduce them where the birds can see each other through a fence for a week or two first. Adult ganders can and do kill young birds, particularly in spring.
Mixing with other poultry follows the same logic. Ducks are the easiest companions because the housing and water needs match, and our guide to raising ducks and geese together covers the practicalities. Breed also matters for how the adults will behave, and the differences are worth knowing before you buy, which our rundown of the best goose breeds for a homestead sets out.
Eight weeks is not long, and the decisions that matter are concentrated in the first three. Cover the niacin, keep the bedding dry, keep the water shallow, watch the wings, and handle the birds enough that they grow up thinking people are unremarkable. Do those and you end up with sound, calm adult geese that will be on your place for the next fifteen years. Our full guide to raising geese in your backyard picks up where this leaves off.

Frequently Asked Questions About Raising Goslings
What Do You Feed Goslings?
Start with an unmedicated waterfowl starter at 20 to 22 percent protein, free choice, then step down to a 15 to 16 percent grower at about three weeks. Never use medicated chick starter: goslings eat more by body weight than chicks and can take in a harmful dose of the coccidiostat. Add short tender grass from the first week.
Do Goslings Need Niacin?
Yes, and it is the single most common mistake in raising goslings. Waterfowl need roughly twice the niacin chickens do. If you cannot get a proper waterfowl starter, add brewer yeast at about one tablespoon per cup of feed, or niacin to the drinking water. Deficiency shows as bowed legs and reluctance to walk by week two or three.
When Can Goslings Swim?
Short supervised swims can start in the first week in warm weather, but goslings are not waterproof until their feathers come in at four to six weeks. They lack the preen oil that keeps adults afloat, so they become waterlogged and chill fast. Five to ten minutes, then dry them somewhere warm.
When Can Goslings Go Outside Permanently?
At four to six weeks, once feathers have replaced down and night temperatures are reliably above 50 degrees F. Move them out during the day first for a week or so before leaving them out overnight, and make sure the shelter is fully predator-proof, since young birds are the easiest target on the property.
How Many Goslings Should You Start With?
At least two, and three is better. Goslings are intensely social and a single bird will be distressed and may fail to thrive. Three also gives you the beginnings of a breeding trio later. Budget roughly 100 square feet of grazing per bird once they are grown, not once they are small.
