I want to relate a story from over 20 years ago. I am a manager at a farm supply store, and one customer had an ancient pickup truck that he used only once a week to travel the 20 miles to town to pick up his chicken feed. A pair of bluebirds built a nest in the holes in the bed where one would mount a ladder rack. He had no option but to continue to use the truck, but it did not faze the birds. The nest would be gone for about an hour a week, but the bluebirds managed to successfully fledge three young.
