Besides having a super cg already it is the only way to make super cg. Also it comes down to when you breed, you can have 1 male breed 5 females easily. So even if my only goal was super cgs, I'd be buying a lot more females than males. Making them more in demand. Male maker cgs are down in price but female makers are still up there with females themselves.
Just comes down to females lay eggs and you don't need as many males as you do females in breeding stock.
