Ihave a "reverse" intergration story...
My leghorns (55s) were integrated with my mixed breed flock as juvies. Everyone did fine (normal skirmishes, nothing noteworthy). Then I moved them into their breeding pen and on their free range days they only keep to themselves. Even the roosters. Other hens are everywhere, but nope - they're sticking to their own flock. They seriously do everything together! (All my other breeds, on their free range days, are singing, "Freedom!" )
