Hey guys I'm new around here, and I hate to be that guy (someone who doesn't know what the heck they're doing lol) but a few weeks ago I noticed one of our chickens had a gravely sort of raspy breathing and was sneezing quite a bit. NO runny nose or swelling though, and her appetite is fine - in fact she is the biggest eater of the flock. Doesn't seem that sick and is quite a happy hen. Still lays eggs dependably. but like I said, she's been like this for a few weeks. We decided to quarantine her for now in case it's a respiratory disease. Appreciate the time folks.
