Query: Works for me!

Bought this in the summer. I have six hens, and they all drink happily from it. I have it sitting outside on a cement block so I don't have to hang it, as it can be heavy. My coop is built on legs, so I can place it underneath and the chickens do not sit on it. It is now winter, and it is still holding up well. Be sure to remove the base at least once a week to clean it, or you'll get algae and other gunk built up in it. That is why I only gave it four stars-It would be better if it the base and the fountain were all one piece.
