I have an established flock of 4 hens (3 sexlings & 1 white leghorn) & a leghorn roo named Peckerhead, all about 8 mos old. There are 2 rd isle reds a few months younger who have finally been accepted by the flock & roam w/ them now, so he has 6 hens altogether. Peckerhead is great rooster; keeps them all together, watches out for dangers & alerts to new food. So we also have 3 new pullets & a cockerel named James Dean about 2-3 months old we kept separate & now I think they are old enough & sturdy enough to withstand a little roo "roughness." What is the best way to go about merging the flocks? Just put them all together & see how it plays out? Should I introduce them to the hens first w/o Peckerhead? We let them roam on about 8 acres so they have plenty of room. Little Jimmy just seems to be more docile & I worry how he will fair w/ Mr. "Cock of the Walk" Peckerhead. It seems some on here like a more assertive rooster like Peckerhead & some prefer a more docile one like James Dean seems to be. Any advice for this novice chicken herder??
