Hi, I purchased some pullets back in July. The next day we got them we noticed rattling breathing, excessive yawning, runny eyes. Since then, it has spread to most of the flock, while many seem to have not been affected at all. By mid September, they seemed much much better, and got more chickens. Now it is middle of October and the first chickens that were sick seem completely over it, but the new chickens are starting to get the swollen eyes and yawning. I have been searching through the threads and all I have really seen is that treatment with antibiotics doesn't really work that well in a flock this size (35) and the best thing is to kill all the chickens and burn the coops. Some thread responses say wait three weeks before getting new chickens, some say a year, and others say I can never get chickens again on my property. That sucks because I love having them! So, I'm wondering if it is possible that they are just passing a cold around? The original sickies recovered and are totally fine now, but a few of the new ones are showing those same symptoms. Some are not sick at all. Yet. None have spiralled downhill lIke I've read in other threads. Thank you!!!
