Please help me! My parents have had these chickens for a few years and one of them has been clucking for 2 days. She's starting to sound like a goose it's really loud. They arent doing anything about it but Im worried she's in pain or something is wrong. She's eating, drinking, and acts normal but wont stop making noise. It's almost like something is caught in her throat and she's trying to cough it up. What should I do? She's pretty old too.
