Here is why you have no calicos. Calico cats have weird genetics for their color. Calico moms will only have tortieshell babies, which usually have no white, just orange, black, usually look brindle. Tortieshell moms only have calico babies. Only female cats are calico or tortieshell, and only males can be males. Orange tabby males some from calico or tortie moms. There is an exception now, that orange tabbies are come out as females now too, so it seems that the genetics are changing.
Congrats on the lovely ones, we are hand raising some right now as the coyotes got the mother.
