This will be my first winter with my ducks and I’m extremely worried. My dad insulated their house very well so they don’t freeze to death on cold nights. He even added an outlet so when it gets cold I can add a small heater in there for them. Their house is not very big it’s only meant for them to be in there at night. I feel like when it gets very cold they will freeze to death outside. I’m in Indiana and The lowest I can remember it getting is -25 F. I will start putting petroleum jelly on their feet so their skin doesn’t get so dry. Any more tips?
