Hi, I am new here on BYC. I have a Rhode Island Red adult hen who had been laying normally. She has now began picking out all her feathers on her belly, won't lay eggs, fluffs out her feathers, & talks a mile a minute if I get close to her, pick her up, or move her from the nesting box. She will scratch, eat, & drink. I don't know what is going on with her. There are 5 other hens in the coop with her, no roosters. Thoughts as to what may be going on? She isn't being cranky to me, but she is to the other girls.
