Sometime this afternoon, Mrs. Owl laid her third egg. Though it is hard to tell exactly, it was likely laid between about 12:30 and 1:20, when she sat very still. She spent most of the day incubating the eggs or preening her feathers. So, the eggs are developing, and the young will likely hatch on different days. Mrs. Owl took a shorter evening break than she has in the past, only 15 minutes, so she is getting serious about incubation.
