Question about duck breeding?

[momma's chickens]

Hi, I have two Blue Swedish hens that I got last year and my friend has two Blue Swedish drakes from last year. All of the these ducks came from the same hatch. I was wondering if I got one of her drakes and put it in with my hens would their babies be okay. I am not sure if they are brother or sister or does that even matter with ducks.

Also my hens have been running with a Rouen drake and a Cayuga drake so how long do I need to wait until I start collecting the eggs to incubate and know they will be pure Swedish.

Thank you vevy much!

it doesn't matter much with ducks and chickens, but we don't do it. We do however line breed our call ducks and bring in new blood now and then.....father on daughter and mother on son.....so on but usually not brother sister.
