I just put several ice cubes trays with fruit and water into the freezer, and I just watered down part of the 3-way hay (oat, wheat and barley) that is in the chicken run, thinking they'd steer clear of it. I've read chickens hate getting wet. Wrong! At least with my flock. Droplets were sprinkled on my Silkie as I watered, and she seemed to like it! Didn't move away. Right after I finished, all three hens had gone over to the wet hay and were laying down in it! So I sprinkled mealworms on it to reinforce the behavior. Here in the high desert, I was worried about keeping the chooks cool, and now it seems I have several methods that should help.
