So- I have a big flock of Welsh Harlequins that I love very much. I also have a trio of Muscovies. They're such cool birds. I keep all of my ducks in a 1/3 acre pen in the woods during the day with pools, and they get locked up in little houses at night. I am not sure what to do for the coming breeding season- don't want to have to sell the scovies to avoid mule ducks. Any ideas that won't cut too much into the size of thier pen? Whatever I do has to be on the cheap. Thanks!
