Hi everyone, Ive had this chicken for about a month, shes around 3 years old and an isa brown. When I first got her I noticed she was shaking her head a lot. As time has passed things have gotten worse. Shes been drooling excess saliva for around a week now, usually clear/foamy. Today it was more thick/mucus like. She has been gasping for breath and shaking her head, with some trouble swallowing. Otherwise she has no other symptoms. Eyes and nose are fine. Not lethargic, no loss of appetite. She doesn't appear to have any sores/plaque in her mouth so I dont think its canker. I cant seem to find out whats wrong so Im hoping someone can help! The next step will be a vet.
