Before the snowstorm last evening, I put all 17 ducks (3 call, 14 flying mallards) into the 10X12 duck shack. The snow fell about 13" and the wind came up to 45 mph, and we have a true blue blizzard here. I should mention that we've just moved this duck shack to the farm, and it still sits on the hay rack trailer, unloaded, about 4 feet above the ground, on wheels. A mobile home for ducks, you could say. I filled it with straw and loaded them in with food and water. Much better than their open pen/small doghouse setup from earlier. This morning, when hubby went out, he heard a hen calling and saw her UNDER that hayrack. I bundled up, went out, caught her. She was alert, but her feet felt very cold and dry. I put her in the shack with her buddies. I don't know how long she was out, or from what crack she escaped. What are the chances of frost bite on her little mallard feet?
