Hi, I have 10 six week old Dominique chicks. My issue is one of the largest chicks doesn't seem to be feathering properly. Still half covered in pin "fluff" feathers and on the the wing near the body(the most sharp curve of the top of the wing) there is nothing. No feathers, just bare spots. Is this a condition I should be concerned about or will the feathers grow in at some point. We are near the point of putting them out into the yard and I don't feel this one is ready. Thanks!
