I ducks readely adopt other paddle pushers
sometimes there slow doing it but every one I on have.
my 5 J-pekin and 2 cayuga ducks and 2 mallards get alone with my 8 3-week old goslings even the gosling try to rule the ducks, the 2 6-week old goslings dont like the new 3-week old one but they run and swim together they just put there heads down low and hiss at each sometimes but I only just entradused the 3-week old a few days ago and there getting better each day, but thats goose politics ducks are much more ready to adopted other paddle pushers, just hold the gosling in your had and sit next to your pekin and see what they do and even let the gosling run around your feet in front of him and let them get to know each other, if the duck is alone it will most likely wont to adopt the gosling, it the gosling that will want to test the duck.
hope this helps, I have 20 paddle pushers 2 6-wk old african 4 3 wk old chinese 4 3 week old touluse, 5 6-wk old jumbo pekin 2 6-wk old cayuga and 2 10 wk old mallards and they all sleep in the same pen and run in the back yard together, but before I turn them loose to sleep and eat together I watch them for a few days and seperate them at night till I see how they get alone.
I got 10 runner ducks coming june 4 from McMurrys and cant wait to see them and intraduce them becuase I've never seen a runner duck in person.
