Forget the ice cubes and frozen water bottles, if your chickens live in triple digits, ice is going to melt in minutes and be of no help at all. In Arizona we have to be much more clever than that!
Mist systems aren’t any good either, because chickens usually avoid them. The best way to help your chickens survive the heat is to give them a more natural way to keep cool. Dig them a shallow pond and put a hose on a slow drip. This will bring up worms, and that’s a sure way to keep chickens interested in staying right where you want them. You don’t have to go to a lot of trouble, keep it simple. Watch the sun, make sure your little oasis will be in the shade during the hottest part of the day.
Put a drinker in different places so there is always water in the shade. If you can’t find find suitable shade, make some. Make use of mesh shade tarps, shade cloth, shade sails, etc. Be creative, I found and old pallet, covered it with shade cloth, leaned it up against a fence, and put a drinker under it.
Today it is 107, by the end of the month it will be 115+, these are brutal temperatures and can be fatal to chickens. With something as simple as a shallow pond, they will be fine. Wherever you live, there is dirt, water, and I’m guessing you own a shovel… it’s that easy!
Tip: if you have bushes or trees by your chickens, spray them with water during the day. Your chickens will be drawn to the cool air around the trees and have a chance to recover from the heat.
