Absolutely maintaining multiple cock birds requires good infrastructure. I've gotten away with a few things in the past with the dorkings only. When I throw them all back together after the breeding season, there are scuffles, but they work it out with little bloodshed as long as there is lots of room. I've also used older birds to teach teenagers their place. I had one Red hen that was the product of my Red xSG cross. She was here forever before I lost her to a predator(mostly because she could fly over and thru anything). She would use her spurs on young cockerels in a very impressive manner. They were always very respectful after spending time with her. She was not a great specimen, but was worth her weight in gold for her broody abilities and keeping peace in the flock. I have no idea if this method will work for me again. That is why I'm not counting on it. My breeding pens are set up with flexibility. My plan is to breed with 4 cock birds in 4 pens. I'll have a couple stand bys in with the layers if I need them. I might not be able to pull that off the first year, but I will in subsequent years.
I think its a delicate balance to breed in such a way to have a wide genetic base so as to maintain vigor, but tightly enough that your birds are consistent. Using clans appears to give the best chance of this based on my reading. And if you aren't breeding for 'it', you are breeding against 'it'. So apparent in dogs and horses too.

Jennifer,
WTHeck??? AGAIN....I could not have said it better myself. 2 of the cockerals range together during the day out in front of the pens. I need to take a picture of that. It turned out nicely and is a good start -- and like the dorkings, not perfect and still a work in progress.
