I have four girls two weeks old this week - 3 BPRs and 1 (according to the general BYC consensus at the moment) Light Brahma. She's the one I have a question. Since I got her, she was the most musical. I could tell her happy chirp and her leave me the heck alone you crazy woman chirp. Today, she has her same musical chirp, but she's got a different sound overlapping it - it sounds like a squeaky swing or a very soft goose honk. Should I be worried she's getting sick or is it just a new sound that's normal for chickens/brahmas? Thanks!
