I went to pick up another chicken yesterday and when I got there I noticed a lot of the chickens were sneezing. I picked one that looked healthy and brought it home. When I got home it was in contact for maybe 5 minutes with my other chickens. I removed it because they were picking on her. Then she started sneezing and her tail was down. I isolated her. At night she was breathing with her beak open and this morning the sneezing was really bad and she wasn't eating. I ended up culling her because I didn't want to risk my other birds. Do you think my other chickens will possibly get what ever respiratory disease she had? I'm never going back to that farm again. I realize now I should have isolated her for a few days to observe her. This is my first time having chickens
