Hello. I have a 6 month old pullet that started coughing yesterday. It's a prolonged hacking type cough that sounds like she trying to expel something from her throat. Today she rattles when she breathes. I looked down her throat and can't see anything. Her crop seems fine. She doesn't have any discharge from her eyes, nose or throat. I'm thinking she has something stuck in her throat. She's acting okay and eating and drinking just fine. Any suggestions?
