A few weeks ago, all my hens stopped laying, on the same day. At first I thought it was just the heat, because they are all young and should be laying for a year or two more. But, they should have started laying again, the weather has been nice for a week. I then thought it could be a snake or something eating the eggs, but I'm out there so much, and there's no sign of that. I've had it happen before. Then I realized, because I culled all the roosters except for one, the hens could feel stressed without them and their protection. Any ideas or advice would be great!
