this is brilliant....I will be trying this asap....my poor girls were sooo hot today. I brought them cool water and some frozen corn and green beans (which obviously didnt stay frozen long but were cold) and that seemed to cool them down someI put water in old milk or juice jugs and freeze them. I put them in the coop and all of mine love sitting by them and sometimes even perching on them! It helps keep them cool for a while, and I just always keep a frozen jug on hand to switch out with the ones that melt.
