Muscovies and a Turkey?

[pdxducks]

I live in the city of Portland and have a 50X150 lot (so the backyard is probably about 50x50). Last Spring we added 3 Muscovies and it has been a great experience. We let them have one clutch and ended up butchering 18 ducks (were definitely more than the yard could support). Thanksgiving has got me wondering whether next year I could add a Turkey poult and raise it for next Thanksgiving. Would a Muscovy hen accept and raise it? My hen did a terrific job raising her clutch this year and I'm much more inclined to this than dealing with incubators and brooders.
Does anyone have any experience with trying this?
Thanks, Scott
