I have a 7 week old (6 and a half actually, turns 7 this Sunday) that does not seem to be feathering out completely... While walking around he looks normal, but when he roosts, lays down, or opens his wings to stretch, the backside (usually covered by his wings) is bare, no feathers at all. Is this normal? Is it just part of the growing up process? I notice a couple patches on some of its brothers and sisters where they lack a few feathers, but not as much as this chick. None of them, including this one, act sick or distressed from when I observe them. If I need to post a picture I can tomorrow. I just noticed it tonight when I went out with a flashlight and I didn't have a camera. I'm hoping its just part of the "growing up" process of the chicken, but I thought I should ask people who knew since I am still new to this.
