It's not a guessing game.
That male is either silver or golden duckwing with columbian gene, so any females you breed him to will throw you silver females and golden males with a possibility of gold/BBR type females that look kind of like New Hampshire hens in color, some of them like your brown and black girl (what some people think is like partridge color) All of those hens will produce the the same results of mixed variations of duckwing with columbian genes, meaning they'll be varied amounts of black markings over a brown body, however since that male looks to be silver, you'll get silver offspring instead. So, they'll end up being white with black markings of varying amount in various regions, mostly the tail neck and back. Some just the tail. Males will look like your current cockerel. The white pullet will produce either solid white offspring with possibly black smudging or offspring that look just like the rest of them. (various wildtype colors with columbian influence.)
From what I see so far, the cockerel looks straight up silver duckwing with columbian. Possibly carrying a Wheaten gene but that doesn't matter too much. If he ends up developing any yellow or orange color, you've got a golden. If he's a silver, you'll end up with a lot of pretty pullets that look mostly white. The cockerels will look a lot like their father. If he's golden, you'll get offspring that look just like their mothers. The cockerels will be like their father, but with golden/orange/red coloration in the wings and back. If the male you're using is heterozygous for columbian, some of your offspring will have pretty salmon breasts on the females and black breasts with white and yellow in the neck/back in males. Basically a normal golden duckwing.
Hope that helps!
