I had a blackstar rooster who was a pretty tough guy. He was in charge of the hens and was always good around the baby chicks. but he was mean to people and to any other rooster. He was about 2 years old when the temp here got around 100 -105 and he died. All the other chickens were fine but i think the heat killed him. he was healthy but he was also pretty big. about 8 - 10 lbs. can a large rooster that is young die from heat? is this uncommon?
