Hi this is my first post to BYC and I need some help. I have a hen who is about 4-5. She stopped laying eggs about 7 months ago and just today I noticed she has some difficulty breathing. She is not cocking her neck she is just sitting with her mouth open clearly having trouble. Today, when I let them out in their run she was walking very weird. I'm not quite sure how to describe it but she was squatting and almost just sitting down refusing to move. About an hour ago when I went to go close them up for the night she was on the ground instead of her perch. This is very abnormal for her as she's never done it before. So anyway is this just an old age issue or is there something I can to to cure her or make her more comfortable??? Update: there is now a pea sized blood clot in her mouth, we have tried calling some vets but its a sunday and not many do chickens.
