Our buff orpington has been laying for a few weeks now. We have heard her sing the egg song 3 times, all were weeks if not a month before she began laying. I know for a fact that she doesn't sing after she lays, I've been there 4-5 times and she just quietly comes out from the box and resumes normal chicken life. Any one else have a chicken that doesn't sing after she lays? I wonder if she will start after the others begin laying and singing?
