When Grandpa was a kid, there were lots of quail. Subsistence farming was the way things were done, and there was a family on every 40.
Each had a cornfield, a garden, a few small row-crop fields, a pond, a cow pasture, a weed-grown junkpile and probably a woodlot.
Fields were small and odd-shaped, turnrows and field borders were uneven and weedy, and in general everything was close together and a little shaggy. And almost every 40-acre farm had four or five coveys of “birds.”
