Well, had a friend tell me this the one who tought me everything about quail gave me cage ideas tips and everything this guy raises over 200 pheasants, way over 4,000 bobwhites, and chukars for realese and he also raises some cortunix on the side, he told me never to breed an A&M to a Tuxedo because they are both hybreds I'm not sure its fact I'm not sure if its anywhere online but I think that guy knows what hes talking about, so my personal view of it true or not I'm not trying it till someone proves him wrong, just thought I'd say it incase you wanted to add that info somewhere or found any info regarding the matter.
