Hi Anna. Since you are from MN I thought I would send along a photo of my Khaki drake patrolling the spring run last February. They are winter hardy and though we had a mild winter in central NY my ducks preferred to be out in it rather than inside their coop. The more blustery it was the better they seemed to like it.
Here is a photo of that same drake and the lone female I had at the time last January when they had a nice straw and shavings lined coop to be in.
