This is my first year with ducks. I have 4, 3 month old Muscovies. I have been doing research about what to do with the plastic kiddie pool this winter. I have heard to remove the pool during winter but so far don't seem to mind the cold. When is it too cold? I read Muscovies don't like the water as much as other ducks mine seem to spend a quarter or more of their day floating in the water. Are they smart enough to avoid the water if they are at risk of frost bite? I don't want them to get frost bite. Some people say use your boot, seems cheap but is the water going to be too cold? Ice sharp ect: Some say water heater sounds expensive and possibly dangerous, aeration, pump/ fountain.. Just wanted to know what all you seasoned duck owners are doing this winter. Thanks for sharing!
