I've read a few older posts. But didn't see anything specific to an older roo... Today I picked up a four month old black australorp and put him in with 16 three month old pullets. He immediately went to work establishing his dominance. He's pecking some of the girls pretty hard but I figure it's just natural domination. He's about twice their size. Should I keep them separated or follow some procedure? I put him in the coop for a couple hours by himself to get hm used to his new home and then openned the door to free range with the gals. Now they're all cooped up for the night. Hope I don't find a murder scene tomorrow a.m.
