Hi everyone, this is my first post and I need help. I have RRR and Golden Comets that have been doing great for a year now. However, just two days ago my husband came home from work to find one of them near death in the pen. The others were pecking at her and pulling feathers out; he tried to save her but was unsuccessful. Just yesterday he came home to the same thing but was in time to save the hen. Any ideas on what could be wrong? Some of them seem to be molting (or something) but otherwise seem in good health; they are eating and drinking well and laying eggs daily. HELP!!
