I have 3 ladies 13 weeks old, 1 BO, 1 LB, 1WTB. When I got them at 4 weeks old the WTB quickly took the reins, but now that she is so much smaller than my other 2 (about half the size) my BO has taken charge. There was a lot of feather puffing and face to face stand offs for about a week, but nothing serious, but now if the WTB tries to get food or treats before Ruth(BO) or Maribell(LB) Ruth gives her a look and she backs off. Is the size difference what prompted this?
