Just posting to illustrate how serious heat can be. Lost a pullet today, young, would have been a year old in August. No signs of illness previous, absolutely zero. Was seemingly fine at 3 PM, found her dead at 5:30 PM, in the shade. My temp currently reads 103 F in the shade. I did a very quick necropsy, her core temp was 116.8 F. Felt HOT inside. Also found a fair amount of abdominal fat and liver showed very early signs of fatty liver disease, very early. Her liver did not hemorrhage, it was intact and there were no signs of any internal bleeding, and all other organs looked normal. So treats will be cut back for all and just wanted to let people who may not realize how serious heat can be for chickens. I do many things for relief from the heat for them, but wasn't enough in this case. Since I found nothing else wrong, have to assume this was heat stroke. Take the heat seriously folks!
