My dear hubby ordered this from a farm supply catalog and installed it today. I've got more hens than I've had in the past and they kept bumping our old 3 gal stainless waterer so it would leak out. I would come and find them upset with no water. So hubby solved that! However, my girls are not chicks. All between 8m and 4yr. I took away their old water can and went ahead and shut them in for the day (they were out free ranging). I've seen a couple of them peck at it... but the others are squawking up a storm at me like they are asking for their water can. I'm guessing they'll catch on, right?
