One of my buff Cochins just started laying on Saturday(yay!). I got my second egg from her yesterday. I've noticed that when I let all eight of my chickens out to free range my layer seperates herself from the rest of the flock. She just goes off on her own. She will regroup if she gets scared but that isn't often. Even when the rest of the flock is frightened and making a b-line back to the coop my laying hen is still out looking for food. She isn't broody at all. Yesterday I heard her version of the egg song. Not what I expected. It wasn't very loud at all but it was a long song. Anyway, why do you think she wants to fly solo?
