Amen! I bought a generator and keep extra propane for the grill. I bought a stock of emergency food, too.
I finally decided to fix an old dog crate bottom for a huge chicken "pool". The lip is perfect for perching. I will put water and ice blocks in to keep it cool. The girls have all figured out that will keep them cool. I covered the run with one of those 80% shade tarps. The Home Depot water bucket gets a block of ice added, and frequent spraying the run keeps me busy.
My favorite is the small battery operated quiet fan behind a frozen milk jug. It really keeps the vicinity cool, and is hilarious watching the hens get their feathers blown.
What we do for fresh eggs and our feathered dogs!
