Is that the show in Inverness? If so, I will be there. Most likely. My grandparents live in Inverness, its a good excuse to see them, and to get them to watch the kids while I get to look at chickens
Your results where from a columbian hen with black cock. I have columbian cock with black hens. My experience with my birchen roo is I get poorly marked birchen cockerels and black hens when he is over a black hen. I figured I would get the same type results (only columbian) with a col. Roo over black hen. I do know that when you use a birchen hen under a black roo (just an example- I want to start a blue barred LF cochin project, and talked to some friends on how to accomplish this. Would use blue cock over barred hens, f1 would have poor barring, but have blues, then breed f1blue cockerels to mother barreds, and f1 blue pullets to father cock to improve typing and keep on... Does that sound about right?) I would get all poorly marked birchens, but to reverse hen and roo, for all intensive purposes, gives you "sex link" birchen cockerels.
This being said, if I where to get a black roo, and put him over the columbian, could I use the poorly marked offspring pullet under my birchen to improve his offsprings body typing, since I don't have birchen hens?
I am slowly, and I mean, slowly, trying to understand this genetic stuff. When it comes to talking about alleles and stuff I get completely lost, so I have to go by basic coloring "rules"
