This will be my first winter in New England with birds & with a barn. My barn is OLD & some floors are dirt, some are wood..and have even started rotting. I know im not going to be able to keep my ducks pool filled since it will freeze- but..what about water?. I have 2 things..how do i keep water in the barn so that it wont get the hay all wet & stinky & how do i keep several water dishes from freezing?. Right now I keep a duck pool & assorted size bins for water. I know the ducks need to be able to submerge their bills & faces.
