I have a 5 month old Ameracauna hen who has started running to me and squatting and raising her backside to me. She also wiggles around ... it almost looks like she wants to lay an egg or something. What does this mean? She has not started laying yet, but about 2 days ago I noticed her 'hips' spreading, I think she is about to start laying. She seems very confused. I have one other Ameracauna that is not laying yet, and one that is. Thanks in advance!
