A cooler. Now why didn't I think of this! I bet this helps keep their water cooler in our horrendous summers. At first I wanted to do an automatic waterer. But I have no trees in my yard at all. So....yeah that's gonna be difficult to keep cool. A local nursery has Moringa trees though so I'll probably go get a couple of those to plant on the west side of the coop. So much to do...why can't there be more hours in the day?
