Lifestyle change for Momma

Momma has had a significant lifestyle change in the last 24 hours. She is no longer trying to incubate the 6th egg and I do not expect it to hatch. Last night she began joining Papa in the quest for food, spending as long as 45 minutes at a time, several times during the night out of the nest box. Once she retuned with a mouse (BTW, I use the term "mouse" loosely to refer to any small rodent that may also include the abundant voles in my Backyard Habitat). Papa brought in an additional 3 mice and several smaller items (probably moths). Momma is doing all of the feeding, entering the box and preparing the meals in bite size pieces for the owlets. It still looks like their eyes are closed but they are certainly increasing in size rapidly.
