I have 12 hens and a duck. I had 2 roosters. I noticed 4 of the hens had major feather loss on their back, and wings and some even around the vent and chest area. I thought some of it was due to over mating and some might be due to bullying. I got rid of my roosters and none of the feathers have started to grow back. I put saddles on the ones with back feathers missing but I don't know what to do for the rest of the areas. I think they are replucking the bald areas as the feathers grow back because I heard it is really irritating when new feathers are growing back. I guess my question is, does any one have any advice and has anyone come back from the land of nakedness before? There is no blood that I can see, fyi.
