One of my coops water has been empty everyday the past week or so. I have three leghorns in that pen and I couldn't figure out how they were drinking so much more than the other pens, so I watched them for a while today. My rooster is spilling the water on purpose. I have hanging waterers and he will take a drink or two like a normal chicken and then jump on the rim and spill it out and drink off the ground. Has anyone else ever had this happen? I guess its not a real problem. I am out there everyday, so I just fill it back up. It is a little annoying though. Any ideas on how to stop this? I sat it up on a block while I was out there and he just knocked it off. Thanks for any advice or comments.
