I like these. I have 5 in 5 different runs. I am having a problem getting all 50 chickens to use them and in the summer heat that is a problem. I love using them in the igloos so that the water is closed and the dirt and debris stays out and you can add ice to help keep the water cold. I’m looking forward to see if the water will stay warm in the winter. Truthfully I replaced one drinker on each one with a cup because I can’t afford to have a chicken not drink in this 111 degree heat and I’m happy that they are interchangeable. I also like the plug on the end so they are easy to clean.
