The little guy in the multiple picture. One closest to camera is different from my others. He has alot more frost on him.No pictures, but they're both duckwing varieties, so the colour pattern will remain the same. Cream legbar is barred, so all of the offspring will be barred. Cream legbars (should) carry gold, which is sexlinked, so with the silver hen, the male chicks will be silver, and the females gold (depending on the colour of your rooster; I believe some cream legbar lines are silver; most just carry a dilution gene that makes the gold very pale, and some don't carry the dilution gene and are very gold) and with the gold hen, the chicks should all be gold.
Crests are dominant, but likely to be tiny little poofs, rather than anything substantial.
