Diversity and introducing young will get the best results. Chickens are pretty racist like that. When I had my three shavers, they were raised with one white silkie, but never tolerated other breeds well when I added on later. Now that they are gone, my flock is pretty diverse with different patterns, sizes, ages and feathering, so they are much chiller come integration time.I do not have one as of yet...I definitely want to add to my flock one frizzle!
Those of you that have mixed flocks do they ever get picked on for being different, odd one out?
Silkies are weird and flock silkie, and one of my two had been raised with frizzles in nearby pens and vice versa for my frizzle, so they have a bit of a broody clique going.
