I have some baby chickens, some are silkies and some are cross-bred silkie/polish. There were also some (2/3) maran eggs. Unfortunately one chick died in the shell and I'm not sure how many of the dark eggs hatched. I know/think that one did. There are 2 little black babies that look sort of similar, so I'm wondering whether I've ended up with 2 marans. Those ones have "normal" yellow legs, not the feathered ones with extra toes. Is that determinative that they aren't silkie-crosses? Thanks.
