Its not a silly question. When they squat they bend their knees so they are a little shorter and they slightly push out their wings. Not fully extended straight, but at more of a right angle. Mine started doing it right before they began laying, and they do it in the morning before we go to get the eggs, almost they are curtseying to accept the thanks for the egg. LOL.It can be pretty subtle, and they often only do it for a few seconds. When you pick them up they stay very still.
We had a Barred Rock we named Lolita after the title character in the Vladimir Nabokov novel. As a young pullet approaching point of lay she would squat so fast and hard she made a thump as she went down on her hocks. Sometimes it isn't subtle at all.
