So I'm starting to wonder what are the signs of a cold duck? I don't think mine are cold in the least and they are sleeping in their pool right now. But I have no idea what to be on the lookout for this winter. It is suppose to hit freezing tonight and the next night so I'm sure they are fine but if this winter was like last we will be seeing lots of 20's for the low maybe a few teens. My ducks have yet to ever go in their house before nightfall.
