I'm not Mary, but I have experience with this. It will take a few weeks. You'll notice that they start to look "ratty" as their feathers come in.Mary, I know about your feathering issue (I've read about it here and on your site. Would I see it in day-old chicks, or would I have to wait a few weeks to know if any of mine will have it as adults?. I realize it's recessive, so if I don't "see" it in this group, it doesn't mean I won't see it in the next generation.
