I tried this waterer it leaks on the bedding one drop at a time. My chickens will use it but they don't like it. They would never touch it when I have their other waterer available. This one doesn't leak if its only filled half way and it annoys me because they are out of water when I get home from work. I don't like making them wait for water. They should have access 24/7. If i fill it more than a gallon and a half it just floods over the edge on to the coop floor. I am looking for something that wont make a mess. They only time my coop ever smells is when there is water involved. Any suggestions?
