We recently rescued 3 chickens from a lady who weren't taking care of them. They were itchy and infested with mites, but it was a few weeks before we realized. One was diagnosed with Cocci and has since been quarantined. Because of this we cleaned and disinfected the coop with vinegar, garlic and essential oils to prevent further spreading and the very day after, another one of the rescues started sneezing. We took her to the vet and he was very rushed and just diagnosed her with Respiratory Disease. We have since been giving her shots of Baytril for 5 days and she is still sneezing. Could it be gape worm instead? She seems to be stretching her neck out and gasping somewhat. They have never been wormed and are usually free ranging most of the day. Also read it could be from mites getting in their nose? Any advice is highly appreciated she isn't liking being quarantined and I feel like it's stressing her out.
