Congratulations on your new babies!
Making olive eggers I see!
I know that head spots are seen with barred chicks, and the CLB father is barred, so it may mean they are boys, but from what I understand, the hen has to be the barred parent to get the sex linking quality. I honestly do not know enough to be very helpful.

You may not get too many responses today because of the holiday.
Good luck and Happy Thanksgiving!
