Help, this is the second hen i've found with the same injury... a deep slash/cut right under her wing. It looks like a razor wire cut, but there is none around! I've been watching my roosters, could they be doing this to them? I have big roos and they breed my hens constantly. I'm afraid that my big roos are cutting open my hens ( i mean like they need stitches open). i dont know what to do?! I think if it happens again i'll get rid of my roosters. Anyone have any suggestions or thoughts?
