After a recent loss of 12 birds to a predator, we relocated and stepped our "chicken security" up a notch. All of our ladies went into the new enclosure. They were VERY happy to be there, especially after spending the last week in the barn. A couple of my girls, about 10 weeks, decided to take a nice dust bath and remain snuggled in the bedding for about a 1/2 hour until I had to actually pick them up and put them into the coop because it was bed time. Before they took their dust baths they were doing this weird squatting thing and just acting a little goofy. In the process of their squatting, one of the bigger "hens" started walking and standing on top of one of them and then proceeded to sit on the hen laying in the bedding. Should I worry...that I may have an ameracuana rooster on my hand. This bird is suddenly bigger and more aggressive than "she" has been. Is this breeding behavior or just chicken behavior. My Mother in Law warned that our girl may be a boy. Any thoughts?
