Do Muscovy ducks get along with other ducks?

[Augustine val]

Hello everyone!
It's been a while since I have posted on here! So my cousin has offered me 2 Muscovy ducks about 1-2 years old and I have 5 ducks that are about 6 months old. Will they be mean to my girls or will they be ok with them ? I don't have to take them because there is another home lined up but what do you think? They are not free range unless I am not home but only once in a while . It's just that my girls are so happy I don't want to upset them!
Thank you

They should be fine as long as they have enough space. And there is a healthy ratio of males to females. There will be a few fights just to figure out the pecking order.
