Went out to the coop to find a horrible shock. Both of my roosters are dead. No major injuries, no blood on the floor. A little around their combs and each had a bloody spur. Their combs were oddly dark so the only thing I can think of was they started to scuffle and over heated. They grew up together and never got into major fights. All my older girls were roosting. My younger birds had been outside moments before. I found the boys when I went in to do a head count. So sad...
