Hi! This is my first winter with ducks. I live in Maine and have 2 ducks, a Pekin & Mallard. It's already very cold, some days staying below freezing. On those days I keep the boys inside their coop. It's very large so they must enjoy having room to walk around but I'm wondering if they get bored? Is there anything I could do for them to keep them entertained? My husband thinks I'm crazy to worry about them, but they are so sweet and I want to make them happy!
