My geese don't like to be enclosed in the winter. I provide shelter for them under a roofed shelter where they have hay and their food pan (out of the weather) this is more to keep the nest from getting flooded in a bad rain storm. Even during a snow storm they tend to sit outside in the open with their feet tucked up and their heads under their wings. They sometimes get snowed over and all you can see are bumps in the snow. When they here us coming with food all the heads poke out of the snow they shake themselves off and come running. We provide a heated water pan and shovel out a clear area for them. If it doesn't snow too heavily they tend to mash the snow down themselves. I have not had ducks for many years but when I did have them they had a duck house and unless I forced them in they would stay outside. My chicken coop has an open wire front with a plywood flap that covers it. I close it at night and open it completely during the day in the winter (other times it is left open). I do hang a red light at night if it is especially cold. I have bantams and they have always done well in the winter. I live in Southern New Hampshire where our winters have reached -20 deg. although we usually only have a few days like that. I am currently building a new larger coop and will probably insulate the walls and floor. It will have a shed (slanted) roof and I will wire the ceiling and have the area between the rafters open to ventilate. I feel that ventilation is more important to chicken health than warmth. My roosts will be on the short side of the coop the ventilation will vent above their heads by 3 feet.I will be using poop boards beneath the roosts and deep pine chips on the main floor area. I will be feeding and watering them on a wide shelf to keep the food and waterer free of wood chips. The waterer and food will be moved out to the run during the 9 months between March and November. I have raised some form of poultry for more than 30 years. My newest coop will be used for broodys and chicken jail during the 9 months between March and November. Not to be confused with the new coop that is under construction.
