This is my first year with chickens. I have 9 hens and 2 roosters. Some of the chickens have diarrhea. Just normal brown color. For some reason those green flies are all over it and swarm the chicken yard. I didn't know if that was normal or not. Didn't know if that could be a sign of something. Maybe worms or something. I have searched the forum and can't seem to find the answer. Only people talking about having green diarrhea. Thanks for your help!!
