Since he has a beard, I'm not surprised that some of his chicks have beards too.
I think he does have blue rather than black, which makes sense considering some of the chick colors.
He does not appear to have barring, so that matches what I was assuming when I was giving answers.
I think Sapphire Gems are a sexlinked cross, where the males have barring and the females do not. If your Sapphire Gem hen does not have white barring, she is not able to pass it on to her chicks either.
She certainly could have a Barred Rock mother, but barring cannot pass from a hen to her...
Yes, that answers the question in the title. But if you read the actual post, it asks "Any guesses on what breeds the hens are that the eggs must have come from?"
They are trying to decide which mix is in each chick, given a particular list of hens and rooster.
A picture of the rooster usually helps, when he is a breed or mix that comes in many colors.
Does he have white barring? If yes, my predictions will be wrong.
The chicks with a yellow or white dot on the head must have a Barred Rock mother, and must be male. That would be chicks 3 and 4.
Does...
