I have not caught who is doing it but today I found two eggs on the sand floor of the coop/run. For the last week I have found at least one a day on the ledge outside the nest boxes or on the floor of coop/run. Dolly (sex link) is OCD about the nest boxes so she is the prime suspect. Some are still warm so they were just laid, some have begun to chill. I do not see how they manage to get them out of the nest boxes without breaking them on the ledge.
