I brought home some new birds from the only person I ever get chickens from. I noticed that one was sneezing after I got her home, and when she sneezed, she had bubbles come out of her eyes. so I put the new purchases in quarantine. When you hold her, she stops sneezing, put her down and it continues again. This is the only symptom. I gave anitbiotics for the past week. These birds are on the opposite side of the farm from my other birds. now my entire flock is sneezing.
