Dorothy laid her fifth egg sometime after 4:00pm today. (See the comment below, it was 4:12pm.)
I’d say she was trying to beat tonight’s snow but in fact she was due to lay one this afternoon anyway.
Here’s her movie from @PittPeregrines:

Looks like it was 4:12.

There were only four eggs at 4:06 if you watch closely 10 seconds in here.
