I'm so sorry about your loss. I know you can't replace that which you losted, but thank god nobody was hurt and with this message maybe you can prevent this from happening to someone else. You are right about the clamps on lights. I had one fall off and almost catch a breeding pen on fire. Luckly, I caught it before anything happen. I now put a nail through the clamp to keep it from falling. Since this happened I've moved and my coop doesn't have electricty. You are also right about the fuses. Fuses and breakers are put there for a reason. To protect you from an overload. Listen to them. Again, I so sorry you had the go through this and lose all your animals that I'm sure were part of your heart . I'm just glad you and your family are ok.
