A BR x BR would never throw a yellow chick, would they? Because I only have one brown egg layer in my flock, and its my BR hen...and the one BR rooster, yet the egg I just hatched from them both is a yellow chick.![]()
2 thoughts come to mind
1. Are you sure they are pure barred rock?
2. White rocks are a result of "sports" from barred birds....so that could be a possibility
