I noticed in May that my hen was losing feathers on her tummy. But in the last couple weeks shes been sitting pretty much all day unless i grab her and pick her up to go outside or walk around. I saw today that she is pretty skinny and has some irritation on the top of her breast bone. I have 9 chickens and she is the 2nd oldest of the group but is also the smallest. my mom said she might just be doing it for the eggs. Shes not even sleeping on the roost with the others like she used to with her buddy. I do have one rooster but he doesnt seem that aggresive towards the other birds...most of the time. She has had problems in the past about pooping on her back feathers. PLEASE HELP ANY HELP WOULD GREATLY BE APPRICIATED!!!!!!!! And is there anything i can do for her??? My Ms. Penny is a sweetheart she is a little over a year old. She is a Golden Laced Wyandotte and i believe that she is a bantie.
