So what is Scout waiting for?

Will there only be one egg in Columbus this year? According to what is "supposed to happen" we'd have a second egg by now. The usual time between eggs is 2-3 days. But, for whatever reason, Scout seems to be taking her time. Both adults have been incubating off and on for brief periods of time, but true incubation (one or the other bird keeping the egg(s) warm 24-7) has not started yet which would indicate the clutch is not yet complete. We are all in "waiting mode" together - watching to see what will happen. It's hard not to get anxious!
Orville continues to be supplying a good variety of prey. This time, a northern flicker was on the menu! (Thanks to Deb J. for supplying the photo!)
