We had a great group of hens and roosters until the 2 of the newer roostesr grew up and became teenagers! These 2 roosters chase the hens day and nite. There is one hen that has been scared of her own shadow since day one. She did okay until these roosters came along and chase her the most and now she has no feathers on her neck. She was hiding in a rabbit hole for who knows how long last month when the neighbor was watching them and supposed to be counting them at nite. I have had her inside to help fatten her up . I take her out supervised and she is still scared 2 weeks later. I chase off the roosters. Is there anything I can spray on her to make her less attractive to the roosters? This hen is the only one that has hair missing from her neck , all the other hens run away. Im afraid the roosters will kill her. Please help save her !
