When we started our flock, we got a RIR hen and roo, and Barred rock and buff Orpington hens. They had obviously not been handled much, cuz they are still skittish, but I'd say on the whole, pretty sweet birds. My roo is huge, but he's laid back as can be. My 3 yo son runs around in the pen, and he doesn't get upset, so I'd say that's a good sign. And my red was my most reliable layer. She died a couple of months ago from being egg bound or something:0( You might have a black sex link with #3, but probably Easter Egger, and #1 is probably cochin, #2 probably RIR, but I'm no expert. Good luck Holy chickens Batman!
