We only had one breed of chickens growing up so I don't know.....Do different breeds get along or do I need to seperate them? They are Year old RIR with a DOMINANT Roo and the "other" Roo with 10 ladies. I am getting some white egg layers to add some color to the flock and different eggs. Minorcas, Rose Comb leghorns, Aconas, or Blue Andalusions as day old chicks. Will keep them seperate until they are big enough to not get pecked too much.
