So I've posted on here before and gotten very helpful advice, so I'm trying again. We purchased a hen from an auction last night and she seemed fine there, with the exception of some missing back feathers, which we figured was from a Roo. This morning we got to check on her and she is making this almost constant sound that isn't quite a gurgle but is a low drawn out almost cluck. So we took a better look and she has a slight discharge on her beak, but her eyes and nasal passages look clear. She is also doing this funky coughing/sneezing type thing. I can't find anything else wrong with her other then that, so it may just be the beginning of something worse. Any suggestions for illness and treatment?
