Hi, I have six pekin ducklings and nine indian runner ducklings that are six weeks old this week. Although I have hatched quite a few times before I've never seen this problem; They haven't grown any feathers. At all. They are still all downy and fluffy and just sort of getting bigger like a normal duck. The Pekins are meat birds and potentially could be killed in two weeks. Normally they have most of their feathers by this stage but these haven't even showed signs of beginning to feather. Are they just a little slow or is it just a weird sort of nature thing? Any thoughts? Thank you, Amber.
