Aww that's too bad, maybe they will stop soon. I have a bunch of hens right now that are getting picked at so much that they have lost a bunch of feathers. I have fed them all flock raiser every since they went off chick food so the lack of protein shouldn't be the problem. The crazy thing is the picking didn't start until after winter. They free range most of the day so being crowded isn't a issue, but by morning more are picked at.Flo is doing ok, all the chickens and rooster is picking on her and i wish i hadnt of got her. I really like her and they havent injured her but she is not happy. I bought her a wading pool and i put food in the water sometimes thinking she will be the only one that can get to it. I was wrong. nothing stops a chicken .
