The thing is rooted within the genetics of contemporary laying hens, which were bred to fulfill the requirements of industrial-scale egg production.

Meat chickens—broilers—have been souped up to achieve weight quickly, supplying the juicy cuts that are white-meat customers demand. But levels are only the contrary. Since additional weight detracts from egg production, leaner is deemed better, and the ones wild wild birds just take much longer to cultivate. Aid businesses can’t justify providing hungry people who have layer-type chicks, which just simply take considerably longer than broilers to achieve full weight—and when they are doing, remain slighter of frame.

The White Leghorn, the egg industry’s ubiquitous layer, is a slim bird with the capacity of producing around 325 eggs per year, nearly one per day—the kind of respected production the industry now demands. To put that into context, hens in 1960 laid simply 150 eggs per year.

Nevertheless the males have zero value—there’s not enough flesh on the bones, specifically for People in america raised on sufficient present day chicken breasts. As O’Hayer sets it: “They don’t wear any meat after all to talk of—they’re scrawny small things.”

But exactly what about history breeds, the hens which haven’t been modified by years of intensive individual tinkering? Those hens do exist—they’re often called “dual purpose,” simply because they could be raised for meat or eggs. They’re mostly the domain of little farms and backyard hobbyists. It does not appear that anybody is utilizing purpose that is dual in large-scale egg manufacturing. Twin function wild wild birds lay less eggs, about 250 each year in the top end, and O’Hayer claims the decrease produces economically unworkable figures.

A farmer might break even at 275 eggs per year,” O’Hayer explains“For a commercially viable product. You wish, but why can you raise a laying hen for eggs that is only gonna offer you 250 eggs a year–and you begin making a revenue at 275–when you might raise a hybrid and you also begin making an income on those final 50 eggs?“So it is possible to feed that bird all”
