Genetics question about feather coloring

[Purple House]

Hi All

I've got eggs hatching right now! The rooster is a splash true Ameraucana from Whitmore Farm. The eggs are from a blue true Ameraucana hen and a Welsummer hen. So far three Ameraucanas have hatched and they're all splash and the Welsummer cross is black.

When I looked this cross up on the chick genetics calculator it said almost anything crossed with a splash rooster would be blue.

So what happened? My Welsummer hen, Petunia, has only been in with this one rooster.

All I can think of is that I possibly hatched an egg from a Welsummer hen and a black Ameraucan roo from a different pen.

Thanks for mentioning this KikisGirls. That is the genetics calculator site I used!

Splash x Black(Bl/Bl vs bl+/bl+) = 100% Blue(Bl/bl+), no chance of that rooster being the father of the black chick

Or maybe the chick is really a dark blue being mistaken as black.
It happens especially if its a newly hatched chick and/ or there is no black chick to compare with.

True.
