Good evening everyone, and Merry Christmas Eve. My name is Mike I live in New Hampshire and I have four blue Swedish ducks that live in my yard. They have about an acre of land to roam on unfenced and also about a quarter acre pond that I have aerators for the fish and that also prevents the pond from freezing. My ducks will not go in their house that I raised them in for the first six weeks. They choose to sleep in the water and then come on the banks of the pond during the day to sleep. They have a nice house with a heat lamp inside of it. I put food in and a trail of mealworms from outside up the ramp inside to where the food is but they will not enter the house. I've given up trying so I just been feeding them outside near the door of the house in the hopes that they will go in at night as the heat lamp is on a timer but no success yet. I know they are a hearty breed I'm just afraid of them freezing to death in the water. Although it was five degrees the night before last and they were fine I still worry. I would encourage any feedback possible. Thanks for allowing me for this long message as I am a new member. Once again Merry Christmas
