Abstract
An automatic enclosure nest for domestic fowl includes automatic controls for controlling the entrance and exit of fowl to and from the nest and for controlling the retrieval of eggs laid by the fowl from the nest. The nest enclosure also includes a trap mechanism that prevents more than one fowl from entering a nest and includes an automatic trap reset mechanism for moving the trap mechanism to an open position after accidental closure of the trap mechanism.
