I went out this morning to feed and 8 out of my 13 chickens were dead!!! They were just dead where they slept. I have no idea what happened. I live in AZ, and it was hot, but it's been hot for months now and yesterday definatly wasn't as hot as it has been. I don't know what could hit them that fast. They were fine yesterday. They were 11 weeks old. So frustrating!!!
