I picked up two pullets from different sellers at a poultry show. One was infested with lice. One was fine. However, since they were brought home together, they've been in quarantine together. The lice issue has been resolved, but now they are both showing symptoms of a respiratory issue. One only sneezes and is otherwise doing fine. The other is really struggling, and I sincerely thought I was going to lose her this weekend. She sneezes, had watery eyes and rattles when she breathes and was really lethargic. There wasn't any puffiness in her eyes, or her joints. I've had her on Oxytetracycline for three days, and while she is no longer lethargic, the rattling in her breathing has worsened. I have them in a warm room and have been providing ACV in their water along with electrolytes. I don't seem to have access to a poultry-aware vet close to where I live. I'm concerned about making the 90-minute drive each way to reach one, causing them more stress, to have them looked at and tested. I'm hoping someone here can provide some thoughtful insight to help this chicken newbie get these girls better, as well as providing an opinion as to whether or not to integrate these girls with my healthy existing flock when (if) they get better. This was my first experience at a chicken show, and purchasing anything older than day-old chicks. So far, it's been a lesson in frustration and sadness.
