hi there, we had 9 B.B. turkeys. A few days ago, I saw all of my birds eating, drinking, and playing around like normal. When my wife came home from work 3 hours later, our biggest Tom was flipped over on its back dead in the back of the coop. It looks similar to what I have read about meat chickens getting “flipping disease” or a heart attack. Any clue on what happened to our poor Tom?
