What is the dominant line

[gmachicken]

What would be the dominant line, the roo or the hen, pullet?

Our BO roo, handsome dude, and our barred Rock bred. The result will be what? I'm wanting to know how big it might be and how large the eggs would be.
The photo of the chick at one day old is not real useful at this time. I will take another in a few days, I'm out of town, just to see at 4 weeks what her? tendancies are.
Any thoughts would be kindly welcomed

Well, you can tell if it is a male or female at this moment.

If the chick has a white dot on it's head, it's male. If it lacks the dot, it is female. You have created a "sex-link."
