I've got the misters up, ice blocks for the water in the freezer, and I'm wondering - is damp ground cooler than dry ground? The chicks (2 Big fluffy silver Wyandottes) hang out under a densely shaded copse of oleander and yucca. I could turn on the sprinkler to get it damp, but I'm worried that the humidity would be bad. It's 89 degrees now at 11:30 AM - it's going to be a tough day. Any advice?
