I might get goats in the summer for their milk but I don't know much about caring for them so I am researching it a little bit. I have chickens and they live in the backyard in my barn.....the barn does not have running water. I just fill up a gallon of water everyday and bring it down their.....a gallon usually lasts the day and night. But I am just wondering if I would have to put a water line in if I wanted to have goats. How many gallons of water does a goat drink in a day???
