With the five in the pen, they seem to be doing okay. There was an additional little EE cockerel in there, and he was terrified of the big roos. I took him out and he has his own little harem now and is free ranging peacefully.
I have so far been very lucky with my males. Next Spring, I'm going to be adding a bunch of hens, but they won't be old enough for several months. I'd try to raise some from chicks now, but I already have four OEGB inside, three rabbits (that are going outside soon!), a blind Silkie and her cockerel friend, and two newly hatched ducklings which will need to overwinter in the relative warmth of my trailer. Last thin I need is a bunch of chirping chicks, lol
