You are going to have a real mix, especially if those frizzles and silkies are mixes which they probably are. Even the Naked Neck is probably a mix. You could get just about anything for color or pattern.
The Naked Neck gene is dominant, so all the chicks that get that gene will be naked necked. I don’t know if that hen is pure for that gene or if she is split. I assume you know a bit about genetics. In general there are two genes at each gene pair. If both of those are naked neck genes for her all her chicks will get a copy and be naked neck. If one of those genes is naked neck and one is not, about half her chicks will inherit that gene and be naked necked.
The silkie feathered gene is recessive. That means it has to pair up, both genes at that gene pair have to be silkie genes for the feathering to show up. So you will probably get a lot of silkie feathered birds, but no with the naked neck. You’ll have to breed the offspring back to a silkie to get the showgirl.
The frizzle gene is kind of rough. It is dominant so if just one of that gene pair is frizzle, then the chick will be frizzle. But it is also a lethal gene when it pairs up. If you cross a frizzle with a frizzle, about 25% of the chicks will not hatch because the gens will pair up. About 25% will not be frizzle because the not-frizzled genes will pair up. But about half the chicks that hatch will be frizzles.
If the black and white chickens have pure genetics, you will either get black or white chicks, mainly depending on which gene is causing the rooster to be white. If it is dominant white genes then you will probably get all white chicks. If it is the recessive white genes then they should all be black. But with silkies and frizzles there is an excellent chance neither are pure. You could wind up with a real variety of chick color or pattern, though the odds of getting some whites or some blacks is pretty high. You could wind up with reds or buffs as well and with a whole lot of different possible patterns. It just depends on what genetics are hiding behind that white and black. With white and black no one can tell by looking.
