I do have an Indian runner. This is my first winter and I've been trying to make sure I do everything right. I still need to get them set up with heated water. I might also get a heater for their small kiddie pool too.
Heated buckets are awesome I cannot say enough about them, For about 5 yrs I use to have to go out muliple times daily and top off buckets with hot water beat the ice open now gosh It's just so nice to make sure they have plenty of water in their buckets but not to have to take a hammer to them. [the buckets not the ducks] lol
What ever you decide on for heating their pool which I don't do I just put them up for winter, since by then my spring is frozen solid. be sure they can't burn themselves on it you know how they like to mouth everything.
