Cream legbar x splash marans

[Kenncarr]

I just hatched my first round of Mar-Bars (Blue Splash Marans over Legbar hens) so far 5/5 chicks are blue with no head spot. They can’t all be girls??? @Toon how obvious was the chicks head spot? Was the head spot the only distinguishable factor?

Pics are of the 3 I have moved to the brooder. Chick #2 has much more yellow down on the neck. But they all have it to some degree...they are also all Blue coloring. 3rd pic is the top of chick #2s head. There is a tiny dot that I don’t see on the others. I would have thought it would be more apparent though...
