Most all of my genetics info I've learned right here on byc. Someone was once generous enough to share their knowledge with me, so I feel I should pass it on.
Males from this cross are barred, and should have a light/cream head spot at hatch. it may be diffuse across the back of the head and harder to distinguish. Females would have solid dark heads, and when they feather out they'd probably be solid black with silver leakage. The leakage on a female shows at the throat/neck/chest area. On a male it comes through in the hackle and saddle feathers, and on the wing bows. I'm thinking as your boy matures he'll develop more silver/white patches in those areas.
Since the father is laced, a pullet might also have incomplete lacing, making for an interesting silver on black pattern.
I had some birds with kind of the same genetics, it wasn't a Polish but a silver laced Wyandotte and a barred Rock instead of a Dominique, but the base colors interacted the same. I don't have pics of the pullets, but here are the cockerels....
If you're interested in learning about sex linked color genes, this thread is a great place to start. Don't be intimidated by the massive amount of pages, all the good stuff is on the first post, with the charts.
