Cocks incubate eggs from 10 a.m. to 4 p.m. Hens are on the job the other 18 hours and don't seem to mind the uneven division of labor. Waving a fisherman's landing net to catch birds for training may spook some of them off their nests, but you have the sexes identified. Your watch tells you which to leave behind. If your training grounds are at a distance, train those birds you won't shoot to fly home when flushed. After they've flown around home, release them a half-mile toward the grounds.
Care is simple, too.
Commercial pigeon pellets are available, but the birds much prefer grains. Provide grit to help grind grain in their gizzards. Fresh water changed daily is a must, but don't get too neat about the loft floor. Wendell Levi, lifelong experimenter and author of The Pigeon, found that pigeons' dry droppings prevent disease better than any other bedding or even floors kept scrupulously clean. Wet droppings are a disaster.
