A buddy has good piney woods with extensive food plots on 1500 acres. Every year he'll put out 50 coveys of 25 birds a covey, six to eight weeks before the season. Once a week, milo is broadcast on food trails. The birds arrive from Alabama in a climate controlled trailer and are raised in an isolation environment where the birds don't see people. By the time the season rolls around, the birds become strong fliers and aren't "kick'em" ups. I won't say they are equal to wild birds, but there are so few wild coveys to compare them to, it's a comparison based mostly on memory. My friend has been a quail hunter for over 50 years and I recall when he would harvest 350 wild quail a year on public land. He doesn't mind spending a buck on quail hunting and swears by the birds delivered by:
