My opinion also as well as most of the 4H moms I've talked to. One shows chickens/goats and she just ranted about the bad judgement of having to exhibit animals in typical mid July Missouri heat. They turned big dairy house fans on their animals but still you have to wonder about the long term stress damage that is done to the animals.
I just went out and gave my birds fresh water and a bowl of blemished tomatoes to munch on. They are all vying for 'who gets closest to the fan' in both of the coops.
I use big 2.5 gallon cat litter jugs to water my birds. Usually I fill them up the night before and leave them for water changes the next morning. By then the water is nice and chilled for them. This morning I left a jug in the smaller run and went back just now to use it. Couldn't. It was hotter than the water that comes out of our faucet.
Still they appreciated the tomatoes. The weather has been so wonky here 80% of my tomatoes have blossom end rot going on them. Sigh. So much for planting resistant plants. At least the chickens love them.
Ya'd think I'd learn.......
