We have been experiencing high temps like most of the nation right now. Three of my E E'S started making loud labored breathing sounds. One even made what sounded like reg. hiccups every few seconds. My DH put the box fan in the coop, I wet down all their bushes and under the bushes, put frozen bottles of water in every water container around the yard and gave them cold treats. After two days only the loudest-wheezing/hiccuping chicken sounded very bad. I even caught her and held her feet in cold water to try to cool her down. The other two were fine. Then I remembered many years ago I was bottle feeding my first calf and it developed diarrhea ( I did not know about scours then). Some old timers told me to fix up some jello water for him and put it in his bottle. The calf loved it and quickly got over his scours. Now the old timers told me it replaced the electrolytes. So yesterday I made up half a gallon of jello water...strawberry/banana...and set bowls of it around the yard. They loved it and all drank from them. Now it hit 102' yesterday...this morning all hens are doing fine. I just placed some more bowls of jello water around the yard. Now I don't know if it is just the sugar in the jello or what but it worked. No hens stressed from the heat now. Of course, Peanut Butter..the really stressed hen...runs when I come near her now.
