hello! I am relatively new to the chicken world. I have a young mixed breed chicken that is suddenly having trouble walking. Yesterday she was ambulatory, eating and drinking and acting normal. Today, I found her on her left side in her coop having trouble getting up. She attempts to walk, however cannot hold balance and falls awkwardly. She will not eat or drink when held upright. Otherwise she is alert and does fight when I try to pick her up and hold her. I did not see any lice or mites on her. She does not have any respiratory symptoms either. Any suggestions?! I really would like to help her if I can!
