Hiya, and welcome to BYC!
@Jenbirdee should be coming along and she raises both and maybe has a story for you.
We've only raised silkie chickens for nearly 9 years then out of the blue a month or so ago, two ducklings got driven out here assuming we'd take them. Okay. So they are around 6 weeks old now I think and sharing a pen with a crossbeak hen. All I know is if they are drakes, to be wary of them around our chickens as if they try to breed a hen, they can kill them.
We're working on a new home here for them that'll be just theirs.
