I'm impatiently waiting for my girls to lay! This is my first flock, my oldest is 25 weeks but I think my Barred Rock, who is 20 1/2 weeks is most mature. She's grown huge comb and wattles and is the loudest of them all (and is my favorite) but isn't squatting yet. Can anyone tell by looking at her if she will lay soon? She doesn't squat, at least I don't think she does.
