They are busy feeding babies. Below is female bluebird on a windy day standing on top of the nesting box with what looks like a spider in her beak. Click the image if you'd like to see a larger view.
One time while I was watching, instead of carrying food as the bluebird was entering the nesting box, I noticed one of the birds leaving the nest with something in its mouth.
It turns out that bluebirds are meticulous housekeepers. The white object in the beak of the bird on the right is a fecal sac containing the waste products of of her nestlings.

After hatching baby Eastern bluebirds remain in the nest for 16 to 22 days. I don't know exactly how many days have gone by since the babies in our nesting box hatched but considering how busy the parents have been bringing food, their offspring must be almost ready to fledge I am so looking forward to seeing the little ones leave the nest. I sure hope I'm here when it happens!
