Just watch them. My cream legbars were beating up on my bieles for a long time, and they still do it from time to time, despite the huge difference in size. After a winter together, they seem to get along pretty well, but the legbars still get the food first and the best spots on the roost.
This is good to know! Thanks! I've been contemplating added some Cream Legbars to my flock but wondered over how everyone cohabitate.
