We use a nipple waterer and a heating base to keep the water from freezing overnight. We have 8 hens (6 months old). They consume about 4 gallons every week. Chickens are curious animals, when I give them a bowl of water, they all come and try it out! But they are happy with their nipple waterer.Yes - I've been checking it often now that we're below freezing to make sure everything is working as it should. Water comes out as soon as I touch the nipple, and I see the girls drinking throughout the day. Thanks for the reply!
