let's talk about ducks... ...I have my Indian runners in a pasture pen. Will they do alright out there all winter? I was thinking I'd put a tarp over they're pen during the coldest parts of winter and maybe a heat lamp. The guy I got them from told me that they're well enough adapted to the outside to make it through the winter, but I wasn't sure if they had retained they're ability to survive the cold during domestication. I live in the midwest, so the winters are somewhat mild... but wet.
