I have a 6 month old EE who seems to have a cold she has a runny nose and is sneezing. She is eating and drinking great and her poop is good. she is still running around and looks like she feels good. these are my first chickens and I'm not sure what to do. I have 29 other chickens and they all seem fine. I wipe her nose every time I go out and check on them, but don't know what else to do for her. any suggestions?
