Mama, I have large fowl. I have 1 rooster and 2 hens. They are the trio that raises my peeps, when they move to the "big barn". They are so laid back it's ridiculous. They don't move any faster then they have to, I can walk right up to them.
My cousin has BLRW. They are nasty! It depends on the bloodlines, and nurture.
That is funny (not the hahah kind..). So maybe it is just that coloring to steer clear of? You know, I have heard that about Pits, too. That the blues are most likely to be aggressive.
