it’s about 30° and snowing here, but not a ton so far. i’ve got my two ducks and they have a small house that’s got shelter from the snow and wind, but it’s not insulated or anything. they have straw so they’re not on the ground, and a heat lamp(it’s far enough away from the straw to not be a fire hazard) is there anything else i need to do to keep my ducks comfy?
