I have the sweetest rock, and because she's my favorite I can tell that noise she makes when she's cooped up and board for the others. You know when the hens go Baaaaaack not the word, that's just how it sounds. She does that all day long but in the last couple of months I heard her make that noise but her voice becomes raspy and she has trouble making the noise. She never did that before! What's wrong? Should I be concerned? I've seen her lay and she's two years old so I know she's not a he.
