Very cool! Can I use this outside? Will it be okay if it snows on/around it? We are currently using a heated open bucket which works well most of the year, but right now the chickens are not drinking as much. I don't know if that's because of the cooler weather or because they don't like the taste of the oak leaves that are falling into their water. I think oak leaves contain tannic acid so I think a closed system would be better for them, but I only have power to just outside the hen house, not in it. Thanks.
