I have 16 chickens and just added 10 Muscovy ducks to the lot. Unlike the other BYC answers to your questions, my ducks come home at dusk to the coop. Stay fairly local and eat regular layer pellets. They love to free range. Messy?? YES! compared to chickens at least. Get plenty of pine shavings to layer up the coop. Keep the run dry as possible to keep smells to a minimum. Muscovies are not a big water duck, so you dont need an olympic sized pool...
My 2 cents!
Good luck.
