Who's the Mommy?

My flock consists of a French gander, 2 French Toulouse females (his hatch mate sister) and an African female.
I have hatched 4 in my incubator and this morning mama French's brood has heads. Instead of shells. Yeah!

Baby 1 10 days old

Baby 2 10 days old

Baby 3 3 days old

Baby 4 2 days old

My slightly more educated guess is saying 1, 2, & 3 maybe pure French. 4 definitely is hybrid African ×French.
