It was really hot here today, 90 plus. I had a couple chickens go down from my Ameracauna pen, I have a few broodies in there, and when I checked on them at 1, some of them were all trying to use the same nest. I commented to them that they were going to kill themselves... I went out about 5 to feed and two of them were down. They're both still alive, I cooled them off, brought them inside where it was cool. I gave them both Nutridrops and fluids. They really haven't perked back up at all, and neither will drink on their own. I am puzzled because one has her head all twisted upside down? Would heat stroke do THAT? They were fine and healthy up til now, no other signs of disease. Any ideas why the one twisted like that? Brain damage? The rest of the pen was fine, just these two hens. I'm really hoping I can save the other one, since its my best typed split black hen, but should I put the other down just to be safe?
