During the hot Summer months it is important for your chooks to stay as cool as possible. In saying that, they are very good at doing this themselves. As long as they have the fundamentals.
Shade: and lots of it.
Fresh cool water: just straight from the well or hose. Offer it to them twice a day if possible in their waterers. Make sure you leave the waterer in a shady place, not in the coop. Please see below regarding ice cubes.
Regular feed and scraps
Ventilation: after the day is done, sometimes the coop is the worst place to be. Make sure your coop has proper ventilation.

ICE CUBES
As with any animal, when you give them ice or excessively cold treats, their bodies begin to cool down. The issue is that after a temporary cool-down (normally about 10-15 minutes), their bodies begin heating back up again. But this time, not naturally. Their bodies have already acclimated to the heat slowly with the rising of the sun, but now their bodies are forced to cool down naturally on their own while the temperatures are already hot and heavy. This can lead to heat stroke and heat exhaustion, especially if you are doing this multiple times a day. This causes the chicken’s body to heat up and cool down over and over again until their systems simply fail and become ultimately stressed.
Instead of allowing them to pick at ice cubes and frozen treats, you can stick a regular ice cube (just one) in their waterer to help keep the waterer at a normal, cooler temperature for longer in the mornings. However, do not add ice water to their waterer on a regular basis, especially once it has gotten extremely hot.Regular well water temperature will be just fine.
