Hello, I have a feather pulling/pecking problem with my flock. It is an all hen small flock of 7. They have a 8X10 coop and a 25X36 yard. The yard has tree stumps, roosts, treat ball and a "salad bar". I feed layer pellets, free choice oyster shell and table scraps with cat food. I read this could be a protine issue? I also read I should bring a rooster into the flock and that it may help. Unsure if this really is a good idea. I thought the girls would gang up on and kill the roo but others say it works out fine. The hens seem happy other than their bare backs and occasional bloody "booboos" but I don't want this to get worse and I don't like the idea of them being in pain. I should also say I never see this happening and they all have feather loss so I can not tell who the bad one is. So, my question is....should I introduce a roo to the flock or is this a bad idea? Any help will be greatly appreciated.
