This has been a long road for this chicken. She started out very healthy a couple months ago, now she's sick all over the place. It started with her eye being very swollen. She was also sneezing, so I was injecting her with Tylan 50 for 5 days. The swelling in her eye has gone down, but she is just standing there. I have to bring food and water to her, because she won't go to get any... Whenever one of her three buddies she's with gets near her or grazes up against her, she screams. Her wings are not droopy, and no diarrhea. Just a swollen eye still (smaller, no discharge, not red, seems to be itchy) and the lethargic issue. What do I do?
