x2, my sebright hen even likes my 9 lb rock rooster over any of the little guys. However, I raised the rock rooster with my sebright rooster, and my little sebright just LOVED fighting and ended up getting beat up for that also. However, the hens seem to do fine.
Oh my lord, my little guy loved fighting, too! His son is a cross with my Polish & it only took the one good beating to change his attitude about fighting with a bigger bird. We are in the middle of a separation with the two right now. LOL He's fine with hens of all sizes, though.
