I realize this problem has been addressed before, and believe me when I say I have tried every remedy put forth on this and other forums. My little Red Star, Cosette, is about a year old now and is in great health. She eats well, lays eggs, and gets along well with her coop mates. Trouble is, she has picked all the feathers off her back and around her neck. She was the rooster's favorite until we gave him away in January (we thought he was the problem). We also thought she was being picked on until we isolated her and discovered she was doing it herself. Here are the things I have tried: black oil sunflower sees vitamins and/or organic vinegar in water higher protein chicken feed yogurt cat food meal worms (they love these) BluKote Dusting for mites Wazine-17 for worms Rooster Booster No Pick Pine Tar (2 kinds) Vick's VapoRub Finally, last week I took her to the vet. She checked for mites and disease - nothing. Cosette is, as I have said, completely healthy. I am almost resigned that she will always be bald, but I just wanted to check one more time to see if there is something I've missed. I absolutely enjoy this web site, and it is the first place I come to when I need advice. It's nice to know there are others who really care for their chickens.
