Could it be because they are ready to lay? All the girls are doing the "squat" now. Well, not all. My Aussie doesnt, she is the flock leader. And neither does my BO Audrey, who is picked up and carried around all the time. She never gets the chance to squat. But my BC and my large and still relatively comb less BO who were until very recently she and timid have suddenly become friendly and more outgoing. My BC actually choose to come up into the house this past weekend and hung out with us. She even hopped up into my lap and let me pat her for a bit. And my BO Mae came up to me and let me pat and hold her. Not at all usual for them. Even though they have both been with us and had us around them sicne they were day olds.
