Diverse flock- will they breed?

[AvaLuna]

Hello, Im sure this is a silly question but I have a diverse flock of 2 white silkies, 2- barred Plymouth rocks,1 buff Orpington, and 1 silver spangled hamburg. Two of them are roosters and I always see the white silkie on top of the white silkie hen. Will they breed/mate with the other breeds?

Not a silly question at all! They will breed and have crossbred chicks.
