Of the 4 babies born from my Slate male Batman and pied female Thunder Cat, Nugget the eldest seems to be a regular green while Yoyo the youngest is a pied with more green than yellow on her. Dodo and Monster, the two middle ones were born with silver white down which means they should be blue series. I can't really describe their colors except that Monster is not a double dark factor and looks pretty bluish sometimes. Can someone tell me if there are specific names for their coloring?
