The male is pied, the hen is normal gray. Your hen also appears to have a pied tick mark, a yellow/white spot on the back of her neck. If I am right about the tick mark, 1/2 of your offspring will also be pied.
The male is likely hiding sex-linked traits like cinnamon, pearl, or lutino. You won't know if he is a carrier of these until the chicks feather out. Any chicks with these traits will be girls.
