We may have 4 eggs. This snapshot seems to show a shadow on the leftmost egg that could be a 4th egg. We'll have to hope for a reshuffling of the eggs so we can get a better view.
During the night, Mrs. Owl had an interesting encounter with a cockroach that got in the nestbox. She noticed it, and tracked it (photo 2), and then tried to lunge for it (photo 3). But the perches seemed to get in the way, and it escaped out the top of the door.
Mrs. Owl had a fairly ordinary night, however, with no feedings after midnight. She did leave from 12:00-12:08am, so perhaps she was given some food then. Her morning outing was from 6:08-6:32, a bit earlier than usual.
