I would love to use a nipple watering system but it gets much to cold in NW CT in the winter. I use a 5 gal metal waterer on a heated platform for the winter and in the summer I add a few of the 2 gal plastics out in the run. I'm always looking for a good alternative, particularly something with more volume. I have 50 hens and 2 roosters and on hot days they will go through 10 gallons of water easy. Makes it hard to get away because they always need a refill in the afternoon.
