We have had chickens for years, have lost hens to raccoons, strengthen repair the coop, and move on. So trouble is not new to us, but this Is weird. They quit laying about 4 days ago and EVERYONE, even my fierce, protective rooster, is hanging out in the rafters and will NOT come down. One hen died, looks like she may have had an injury like a bite that got infected but we are not sure, and another hen died but we don'f know why. What is going on??
