I have 4 White Leghorn Mix pulleys that around around 12-14 weeks old. The Rooster was a Olive Egger and Hen was a White Leghorn. Will they lay only white eggs or is there a chance they could lay colored eggs?
Depends what genes your OE rooster has. If he had a copy of the blue gene each daughter will gave a 50% chance of laying green and 50% chance of brown, if he doesn't have a copy of the blue gene all daughters will lay brown.
You won't get white since the OE rooster has genes for brown which is very very hard to get rid of
