I'm guessing this question must get asked often enough. I got 4 chickens last week. 1 leghorn, 1 red sexlinks, and 2 black sexlinks. The blacks seem to have become quite used to us, perhaps even liking us at this point. When I go into the pen to feed them or water them or whatever, the blacks often crouch to the ground, spread out the "elbows" of their wings, flatten their backs, and do a "pat-pat-pat" dance with their feet. Also, sometimes when I'm just looking in on them, one of them will lower her tail. I'm guessing this is a submissive behaviour? Is there a name for this behaviour? I've tried to find this information myself on the net, but can't seem to pull anything up. Thanks.
