I've been using BYC for years and i finally created an account because I had something so insane happen that im still in shock over. We had a flock on 6 hens and 1 very large brahma rooster. We have an auto door. We left to see 4th of July fireworks at a friend's house, which is usually fine because of the auto door. Our dogs were inside because of the fireworks. This morning, my daughter went to feed the birds and came back in tears. Our entire flock is gone except 1 hen. Our rooster was found in the front lawn with no head (typically a racoon), but the weirdest part about this, the front lawn is near a major road. Every predator attack we've had has drug them to the back near the dense woods. But, our rooster was found there. There were feathers all over the pastures, side of the house, near the coop. There was blood on the coop door. Every bird is missing except just one lone hen. We manually put up thr hen tonight, no one else has shown up. I was hoping some were scared and would reappear. There were no other bodies. Im devastated and at a total loss. All I can think of is that the fireworks had a portion of our flock roosting out in the yard. Not sure what happened with the auto door... it was only a 3rd of the way open this morning. I have unplugged the auto door just in case its malfunctioning and manually closed the door for our remaining hen. I honestly dont think I can own chickens again. I've lost one or two over the years, but the whole flock in one night? 5 hens and 1 rooster.... its devastating.
