I have 2 for my chicken yard (apprx. 50 chickens) and absolutely love them. My large breed chickens have no problem drinking from them. Very easy to clean and works great all the time. I have nothing bad to say about the waterers. Just make sure they sit on a flat level surface so they do not overflow.
