We had 8 free ranging muscovie ducks and a fox killed 2 on us in one weekend. The 6 remaining ducks we now keep in an old chain link dog kennel, at least for the winter while the fox and other predators' food is scares. We built a rough shelter with no closeable door, just an opening but it's plenty long enough for all of them to get inside and snuggle down for the cold, windy and sometimes rainy nights we get here on Cape Cod. I lined the inside with clean straw and even put a food bowl in there but they WILL NOT USE IT. They go in there during the day sometimes and they eat out of the bowl but they sleep on TOP of the house- all lined up with their backs to the wind and rain! I've gone out in the morning and they all have frost on their tail feathers!! We put a kiddie pool out there for then to swim in but when it's cold out (like the next few months promise to be), the water freezes up quickly and I have to haul gallons and gallons of HOT water out 3 and 4 times a day to make sure they at least have something to drink. Our chickens have no problem sleeping in their house at night and neither do our goats but these ducks want NOTHING to do with the house at night! What do I do? Short of buying or building a shed for them with doors that close (Which is what I'd LOVE to do) is it ok for them to sleep out in the elements like that? I know wild ducks do it but they also swim in the rivers and on the marsh where we live to warm up. I'm so afraid they will get frostbite or just freeze to death one night! Anyone have any ideas!?
