I have a 1.5yr old broad breasted white hen. I have noticed she lookes like shes molting,shes loosing feathers on her chest and has pin feathers. Well today I went out and noticed she has little blister like sores on her head and chest, any idea what this could be? I thought maybe ants got to her because she keeps tryin to sit but there so many of them and so spread out. She is the sweeest thing, I hate for her to be sick and suffering because I dont know how to help her. I tried to research but cant find anything. Help!!
