Hi, I have a coop containing 15 black australorps, 1 rooster and 14 hens. the problem is that they seem to have most of their feathers either gone or broken, it would seem that there is a feather picking problem, the other problem is that the feathers don't seem to ever come back, there is the odd quills coming in but they still look the same as they did months ago. Whats the problem and what can I do?
