I’m just noticing my ducks wing is bent out. I’m not sure if Donald is a boy but I believe it’s a Rouen. I was supposed to have two Pekin Ducks. It’s about 5 weeks old maybe 6
It is the start of the flight feathers growing in. They are large and they are heavy and ducklings are awkward at best. Keep an eye on it. As the feathers pop out of their sheaths it should all straighten out nicely and lay flatter against the body, but if the wing turns outward increasingly it could be the start of angel wing. Keep up the vitamin B/niacin levels while feeding too.
