Hmm....The sand idea sounds good to me. There is just soil under all of that and the chickens will scratch the straw around to get to the dirt to cool off in. I think I will go do some price comparison on some sand!
With the DE, do I just sprinkle it around under the deck where they stay most of the time? What about the nest boxes? Hubby likes the idea of using it as a pest control too. I just read that "When the ants or other pests come in contact with the powder, it is like stepping on broken glass, they will be killed or abandon the area." I showed that to him and his eyes lit up lol!
