I have a flock of 10 hens of various ages and breeds. They all molted between Nov-Dec and some were starting to lay again. For the past month I've been getting 2-3 eggs a day (I'm guessing 4 chickens were laying). And I got my first olive egger egg 6 days ago. Then 5 days ago they all stopped. I thought maybe they were laying else where, so I started keeping them in (they free range a few days a week usually), but two days on lock down and still no eggs. I searched the coop, run and nest boxes and nothing, not even broken eggs or evidence of nesting behavior. Everyone seems healthy, good appetites, very active, no parasites. About 8 days ago they ran out of food and got pretty low on water, it was likely about 24 hours before I noticed (I know, bad chicken owner). Would this shock them enough to stop laying? I'm baffled. In the 4 years I've had chickens, I've never had this happen.
