"What I use to house ducks (and other poultry) is a calf hutch. This is a massive 'doghouse' that dairy farmers use to raise a calf in. You can buy new ones at the feed mill but I got most of my by running an ad in my local weekly paper asking for cheap secondhand calf hutches.
For an enclosure around the calf hutch, I have 2 old dog pens made out of panels of chain link. (It doesn't work for my dog because she's an escape artist). These pens are great because you can move them from time to time (if you are strong enough). Because I can't afford to buy more dog pens, I am also using cattle panels (also available at feed mills/farm stores) which are 16 ft long by 5 feet high. I have to cut the 16 foot lengths in half to get them home in my truck. I then cover the individual stock panel sections with chicken wire, and then I can assemble them into pens around the calf hutch--- pens which can be broken down again and moved easily."
I am curious how this works in cold climates during winter. Do you insulate? if so, how?
