Find pigeon racers as they always sell them.

Go to a farm with them and start feeding them. get them trained then come back one day and throw out some bird seed soaked vodka and semi dried on the outside. Wait a few minutes and go pick all the drunk birds up. I watched an old lady in my neighborhood do it when younger. She and her husband just loved squab. I was never over for diner, just a bored teenager, sitting on the porch, listen to the older folk and getting educated.
