Mum is CreamLegbar, Dad is Marans. Any chance of auto-sexing baby chicks?

Hello everyone, I wonder if it was possible to determine if baby chick is male or female, given that only the mother is cream legbar (the father is Marans). Here are pictures (they are 2 or 3 days old only...)

As long as the Marans father isn't a cuckoo Marans, chicks from that cross should be sex linked. Males will have white spots on the back of the heads, and females won't. However, the spots may be difficult to see due to the coloring of the chicks. Later on, males will be barred and females will not be barred.

Bet the yellow one turns out to be a boy and the rest girls. I’ll be following along to see what happens
