I just had a bird die. Of course, it was my daughter's favorite. I think it may have died of heat stress, but I am not sure. She was fine this morning. I went out and checked on them at an hour before lunch, and I saw her panting in the coop. I thought she was fixing to lay an egg. All the others were out free ranging in the yard. When I came back just a few minutes ago, she was dead. I did notice the top of her head had a bloody mark. Do you think one of the others may have pecked her too hard on the head and it killed her?
