One, two, three. The pen checks the eggs before returning to the nest.
When I arrived at the nest this morning the pen was drying off after a brief time off the nest to feed. Look at the lower left corner of the frame. I'm afraid that's another egg. I hope I'm wrong but I could on;y see two eggs in the nest today.
The cob sails up to a passageway through the break wall in the nest area.
