I have what I think are a Splash Andalusian hen and an Andalusian hen. They are always getting there feathers plucked out by the other chickens they live with. The chickens are not pecking them they are just pulling out and eating their feathers. All the birds have grown up together and we havent had a problem with it before. Is there any thing I can do to keep the other birds from plucking feathers from my other birds?
