I'm pretty new here and I've been entertained and enlightened for hours on end. All the ducks are beautiful and hysterical. This is a great site. But... Here's the thing. I've read that ducks are cold-hardy - they go out in the snow, swim around in freezing weather. I've watched mine skate on their pond and wait for me to break the ice. But I live where it can get down to minus 40. They have what I believe is a cozy duck house, insulated with straw (because they try to eat insulation and plastic) between the walls. I have a heated water dish and lots of straw for them to sleep in, but this doesn't seem like enough. I have a heat lamp but I'm afraid that if I use it 1) they will somehow disassemble it and try to eat it or 2) it will start a fire. I don't want roasted ducks! Also, their house needs to be vented but not drafty. Well, isn't a vent used to create a draft? What's the difference between a drafty house and a vented house?
