I can see my birds favor the Cream Legbar traits. The bird above, the second from the left, looks a lot like her. Yet she is getting more red on her face than your pullets. Her comb isn't quite like theirs.
Are your boys nice birds? Is that a Legbar trait?
I find myself wanting a few Cream Legbar hens now. I really don't have much more room but I am so addicted to chickens. I really got it bad this year.
