I am new to breeding/genetics but find it really fascinating. I recently purchased bbs pure ameraucana eggs from a local breeder. They are due to hatch tomorrow. This week she found out some concerning news. Her blue ameraucana roo, who always produced pea comb SOP babies with other ameraucana pure hens, sadly made all babies with straight combs when that same roo was mated to a maran hen for olive eggers. This was the first time she bred outside of using her ameraucana hens. My questions are: is this concerning and does this make that said blue ameraucana roo not a pure bred? Should I not use the babies from this blue roo mated with the pure ameraucana hens for my ameraucana breeding project?
Is he the Only Rooster with those hens? If he is the only one(no chance of another roo mating with the Marans) then that confirms that he is indeed P/p+. Also the chance of those Ameraucana/Maran cross hens laying Olive eggs are slim to none since the Blue egg gene is linked to the Pea comb with a 2-4% chance of crossing over(Oocyan mutation crossing to the p+ single comb mutation)...
If we assume that he is P/p+ then that means that at any point of his ancestry there was a cross made to another breed(not unheard of), most likely to introduce a desirable trait...
