Squatting is when they squat down in front of you with their wings slightly spread out. It is their recognition of you as the dominate roo/hen. It is also what they do in front of roos or dominate hens to show submission. If you go on youtube, you can look up egg song to hear what is sounds like. I did that so I would know. My girls just started laying so I know when one will be laying an egg. However, as I have learned, the egg song is not alway sung for egg laying. They use it other times as well. I have a pullet who makes no sounds whatsoever when she is going to lay/lays and egg. However, I have noticed that the other girls will all sing the egg song collectively for about and hour or two before she lays. Weird but true.
