Muscovy ducklings, can I put them in the same penned area and coop with my four pullets?

[cchase25]

Hi, I just got 6 muscovy ducklings (maybe few weeks old) and I have 4 pullets that are about 3-4 months old. Right now I have the ducklings in a chicken tractor and a cage indoors at night. I was hoping to lock them in the chicken coop with my four pullets when they get a little older to keep them safe at night from predators. Any recommendations?

Male muscovy ducks are known for injuring and even killing female chickens during breeding season. Duckss are notorious for wanting to breed with any bird that comes thier way... But it's certainly been done before.
