It's impossible for them to be laying anywhere else or under the coop. They've always used the egg box and I am constantly seeing them from our french doors. No egg song either. I think it must be the introduction of new hens. They are jealous and are on strike.I would examine your coop again, Mary. When I had some makeshift coops one summer and 15 layers in them it looked like they stopped laying. Instead, they had dug under the coop and I found over 50 eggs down there. It's too warm for them not to be laying right now.

No, They can't reach into the nest box. Besides when they are outside I'm supervising them. No one can have excess to yard from the outside of the property either.
