Our baby chick, Pumpkin, has a slight runny nose. I have heard of a disease(forgot the name) when a chicken gets a runny nose and it has a bad odor, and it isn't clear. and also there is swelling on the face with that disease. But our chick has a small runny nose, and the mucus is clear and doesn't have any strong or nasty odor. Her face has no swelling and she seems curious and active(loves taking "dirt" baths in her brooder, although there is only newspaper in there LOL) and she is eating her chick starter and ground corn daily. She has fresh water, too that she can get access to anytime she wants. If she has a runny nose, is it something that is serious and is it harmful to the rest of the flock? She is all by herself in the brooder, since her sister recently died for some reason. She also sneezes once and a while. Any ideas on what his is and what to do???
