Do all chickens sing the song? I have a BLRW girl who should be laying but she isnt. She is huge, very red in the face, I can put 3+ fingers between her pelvic bones, BUT she doesnt squat and has only sung the egg song once and she was faking me out with it. Anyways, I am tired of looking in the coop all day so should I just wait for the song and then go look?
