Hi Bayard Chicken folks. I noticed today that my Buff Brahma pullet (not laying yet) kept making repeated, low, cooing sounds. that's the best way I can describe it anyway. She didn't seem to be sick and I figured she's just becoming a vocal hen. Later in the day, I also noticed she was repeatedly stretching her neck out and opening her mouth. Kind of like a yawn. But no sound or anything. Then I went and checked on them about an hour after they settled in for the night and I still hear her making that cooing noise over and over. Is she sick??? Please help, she's my favorite hen. thank you.
