I have a few hens that have the feathers stripped off her back, one of them has been bleeding some. I thought it could have been the roosters but then I saw a that a hen was the one pecking her back. So I would like some chicken saddle ideas, I've tried one that slipped over her wings and tail but she keeps on slipping it off. Thanks P.S. If the mean hen keeps it up should I separate her for a few days.
