WTB roo x Maran & WTB roo x Barred - gender?

[ulifarm]

When and how can I tell the gender of these chick crosses: WTB roo x Maran hen chicks or WTB roo x Barred Rock hen chicks?

I have 11 chicks of these crosses! TIA!

Sounds good! So the hen chicks will be olive eggers then.

If the wtb has the blue egg gene it should create olive eggers unless it only carries one blue egg gene then offspring would lay half and half
