We lost a Light Brahma last night. She was found, legs up, with a spot of blood on her head. One eye completely closed the other half open (I don't know if that matters). She was not egg bound, her crop was not impacted and there was no illness. All the chickens appeared normal last night and all appear normal this morning, death aside. All are eating, drinking etc. There is no wheezing, sneezing, smelly poop, discharge....nothing. I am at a loss to figure out what happened. Our chickens do all roost in the rafters of the barn with are about 7 feet off the barn floor. Do chickens spontaneously fall? They have perfectly fabulous roosts on the floor, but refuse to use them. If they can fall off a roost, why would that occur? Help?
