I'm still pretty new to this whole chicken thing... this is the first time I've raised any. I noticed today that my chickens have damp feathers entangled with shavings stuck on their sides under their wings. I think there's a problem with my waterer getting crooked and leaking, which I can fix, but I have no idea how they got like this. Should I give them baths? Comb them? Is this dangerous to their health?
