Mitch, You have the advantage on most of us by actually seeing Lyle's set-up. Does he keep breeding pens with trios/quads/groups from his line and then the same for his birds from Sigrid?....or does he have two separate flocks that pretty much breed "free choice" amongst the flock? I don't have the set-up to have many different breeding groups so my flock is together and pullets/hens gravitate towards particular cockerels/rooster. Last spring, I only had my two original roos and hens. The two roos were raised together but once breeding age, would fight and there was no peace. I separated one into my layer flock and left the other with the two Icelandic hens. I hatched 44 chicks from him (Ari) and the two hens. He was the aggressor in the fighting and crowed so much my DH (dear hubby here on BYC) complained. He was culled and the flock was combined. The end of this month, I will be putting the pullets from Ari with a cockerel from Audun. Mahonri will be getting some of these eggs shipped March 12 (we have annual hatchalongs here at BYC ex: setting eggs on St. Patrick's Day, March 17, to hatch the day before Easter=The Easter Hatchalong. See the Incubating and Hatching forum on Ground Hog's Day for the start of that thread. Right now Mahonri is hosting the Ground Hog's Day hatchalong and that thread is here : https://www.backyardchickens.com/t/618452/ground-hogs-day-hatch ) Okay, back on topic.........I asked Sigrid once about pairing particular birds her answer is in post #573 of this thread, which is page 58. You can "jump" there by clicking on the dots "....." listed at the top or bottom of the thread that have the page numbers of the thread. Once you click there, you can move the arrow or type in the page you'd like to jump to. I could just paste it here but then you won't learn how to "jump" in a thread and you might need to do that if you trying to read through a long one...........like this one!!!!
