Well all ducks should get along. With pekin, black swedish and rouen as long as the fence isnt so big they can fit through height isnt a problem because they cant fly. Call ducks you would need an an aviary or clip their wings. They can fly!Great! Also do pekin and Black swedish get along? I was thinking of getting Rouen, but i don't want ones that might be able to fly. How high should my fences be would you suggest, though i might have it all covered for predators.
