We have a problem here at the Fox Farm. At first one of our hens was fuzzy on her back at the base of her tail. Then bare. Now, all the other 5 have fuzzy picked at feathers at the same spot. So 6 of the 7... ONE lady is in perfect condition and thats the one we have noticed is pecking the others !! Please offer up any ideas as to what we could do to stop her from this behavior. I don't have a lot of choices as we live in a neighborhood with only the one coop and run. Only 7 hens NO roosters... Im hoping for an easy solution but realize that may be hoping for a lot.
