I just bought some chickens from someone that brought them to my house- they seemed to be fine but after 4 days I noticed one of them not moving much- I looked closely and saw she had a runny nose and was making funny noises when she breathed (kind of like gargling) and the eyelids on one of her eyes were sticking together. I am thinking of returning the chickens, but I am not sure how long they have had this problem. After another day, I noticed more of the chickens were showing the same symptoms. At first, I believed that this is the way I received them- with some kind of problem. However, after reviewing some posts on the forum, I saw that moldy hay can also cause some of these symptoms. I have put a lot of hay on the ground for them- and some of it may have had some mold on it. At this point, I would like to try and figure out who is at fault, but even more, I'd like to try and make sure the chickens are alright. I am not quite sure what to do at this point- do chickens get these symptoms when they are around moldy hay or did these symptoms already come with the chickens? Either way, how can I help them get better and should I return them?
