We use 10 ft. X 12 ft. X 51/2 ft. high floorless, portable field shelters housing about 75 birds each to grow these 8-week meat birds. Moved daily to a fresh pasture paddock, these birds receive fresh air, exercise, sunshine, and a clean living area. They are able to freely forage for bugs and grasses, while also eating as much of their wholesome, un-medicated, grain-based, animal by-product free feed as they want. Integrating cows to mow ahead of the shelters shortens the grass and encourages ingestion of tender, fresh sprouts. At Fili-West Farms, we want every animal to eat as much salad (green material) as its full genetic potential will allow.
