I noticed two or 3 of my hens have feathers right above their tails that seem to have been broken off. The only rooster I have is a little bantam cochin. He does jump on them and this is were he tries like heck to hang on. lol. I was thinking maybe he was breaking their feathers. What do you think? I have checked for mites and lice and haven't seen anything. Not that I really know what to look for.
