answer:Poultry adapts pretty well in freezing temperature. Are any of your ducks or chickens equatorial or heat-loving birds? If that is the case, I don’t know what to tell you to be honest. Otherwise, the main issue in very cold temperatures is keeping their water supply from freezing and/or keeping them from spilling the water and getting themselves wet or the ground around the water wet. The shelter should be dry and draft-free, but not air tight or you will get humidity which isn’t good in subzero temperatures.
