Hi folks...I have i5 Buff Orps. 18-months-old and 15 Buffs 18-weeks-old. They are free-ranging together and go to separate coops at night and I was about to have them all going to the same coop. One of my 18-week-old pullets has what I think is a breathing problem. When she inhales there is a raspy growl type sound and when she exhales it sounds like a kitten meowing. I gave her a little Nutri-Drench by mouth and I swabbed some VetRX into the roof of her mouth and the Q-tip came out with a little blood on it. I have her isolated but really don't know what to treat her for. If you know anything about her symptoms or how to treat her, please reply. I went to check this morning and one of the older hens was in a nest box with the same symptoms and several of the other hens are make a sneezing noise. I have two other flocks on the farm EE and CCL that free range in different areas and they seem fine now. These are my first sick chickens so if I need antibiotics I need to know how to treat the whole flock or other meds that you could suggest. Thanks!
