Meat chickens are a quick turnaround: in 10-12 weeks you can raise day-old chicks to roaster size. This means a quick return on your investment. You can also do more than one batch of birds a year.
Meat chickens are space-efficient: you don’t need a lot of land to raise some chickens, even on pasture. A batch of 100 birds can be confined in about 1/5 of an acre without harming the land.
Meat chickens are time-efficient: caring for pastured poultry should only take about 20 minutes a day. This leaves time for other farm activities.
