I can't imagine trying to conquer the Orpington type and fluff all over again! That sounds rough. I think there were some folks i used to know up north breeding ameraucanas or EEs to RC leghorns. That was actually a petty good cross. The blue egg gene certainly did disappear fast! It would be interesting to repeat the process Buddy did with a good lavender ameraucana and have a totally separate RC lavender leghorn line.
