Very hardy ducks.
I used to raise them myself on the Llano Estacado.
If a critter can live there...well...Arkansas should be NO problem.
I watched one day as the hippy mantra "man is the only animal that rapes" was proven to be false. That little gal could sure move but the boys were too fast for her. Not only was it rape..it was gang rape.

I seem to remember reading that Muscovies are actually ducks...they're some other kind of water fowl...dunno.

The eggs are tasty..
