WILL HENS (CHICKEN) ACCEPT YOUNG MUSCOVIES?

[Fawn and Fam]

We have two 5 week old pullets. Later this year we plan on getting 2-4 muscovies (male & female) hatchlings. We will have them in our house till they are ready to go out. Then they will be sharing the same 4'x8' coop and 20'X8' run. I'm wondering if my 2 young chicken hens will accept the younger Muscovies and vica versa? My cousin has both chicken hens and male and female Muscovies together in the same size coop- though they are free range. She said one chicken hen hatched one set of Muscovies and one Muscovy hatched a set of chicks!
