Some examples of calm breeds? I've been looking at:
-Splash Marans
-Silver Laced Cochin
-Easter Egger
-Bantam Barred Rock (would be the flock established with the silkie)
Introducing these breeds a year or so later:
-Speckled Sussex
-Australorp
-White Leghorn
-Cream Legbar OR Olive egger OR Delaware (or another silkie?)
I have ameraucana and EE which have been ok. The rocks I had tried to kill the first silkies I got. The brahma tried to bully them, but I had the genghis kahn of silkie roosters by then. He lead the hens on a mission to dominate everyone. That ended up with all the large fowl terrified of silkies.
