Need some input/advice. I have a chicken who otherwise seems healthy, however, she stinks! It is gross, but it smells like rotten meat and her tail end is always messy. I have washed her two or three different times, tried worming and antibiotics, however, nothing seems to work. She lays monster eggs, (I throw them away) and I have her quarantined currently. She eats and drinks normally and doesn't act like anything is wrong with her, but something is terribly wrong! I can't bear to cull her and would love to make her well if I only knew how. Does anyone have any suggestions or thoughts on this?
