I think my pekins are losing their down in preparation for their feathers coming in, but since I am used to chickens and not ducks I figured I would ask. I know in chickens I don't usually see bald patches but I have noticed in my 2 older pekins that they are both getting thin patches and some patches where there is no down, they're about 2.5 weeks old. I haven't seen any actual feathers coming in yet so I am a bit worried I am feeding them wrong or something. I know the others aren't pecking at them, I keep a close eye on that, plus the others are all much smaller and I doubt they could reach my pekins backs. Is this normal?
