I have a 1 year old Easter Egger chicken, coop is shed with straw. She displayed syptoms this afternoon, she was acting fine yesterday. This will be our 3rd chicken over course of 3 months that had these syptoms. The others died the next day after noticing symptoms. I tried natural remedies (obviously unsuccessfully) but I can't figure out what might be. Vet care is unfortunately not an option. Check for lice and mites but don't see any. She is wasted away though, her breastbone is severely protruded when I was feeling her all over. I have not dewormed them. What can I do for her tonight and for rest of flock.
