My hen has been having a really hard time breathing when she is stressed. Last week I gave her a bath and I swear she was going to die because her breathing was so horrible. She was gasping for air and I kept hearing this raspy noise. She is somewhat fine now but her breathing worsens when she is picked up. None of the other chickens are having a hard time breathing and we havent changed anything to her diet or living conditions. I'm not sure what her poops look like but I dont see any abnormal ones laying around. Does she look sickly? This was her when she was younger. Is it normal for them to change color so much? So what do you think is wrong with her?
