Can I raise broiler chickens on pasture, and what changes?

Broiler chickens can be raised on pasture in mobile tractors or with access to sheltered outdoor runs. Pasture provides room to forage, but grass and insects do not replace a complete broiler ration. The biggest changes are greater exposure to weather and predators, more work moving housing and water, and less predictable growth and feed efficiency.

Provide shade, rain protection, airflow and a dry resting area, with secure housing against local predators. Move tractors before manure builds up or the ground becomes muddy, and avoid leaving birds on damaged pasture. Young chicks need a protected, heated brooding setup before they can handle outdoor conditions; feathering, weather and their behaviour matter more than a fixed turnout date.

For example, the supplied Cornish Cross plan uses 150 birds in an open-air pasture tractor at about 70°F, with approximately 323 square feet of floor area, or 2.15 square feet per bird. That is a planning allowance, not a guarantee of adequate space in every season. The target is about 5.7 pounds live weight at 49 days. Its realistic feed conversion is 2 pounds of feed per pound of live-weight gain, compared with the supplied standard benchmark of 1.72, so budget for the pasture system rather than assuming benchmark performance.

Keep complete feed and clean water readily accessible, and track feed use, weights and losses rather than judging progress by appearance. Breed nutrition specifications and FAO feeding guidance support starter feed for roughly the first 10 days, grower to around day 24, then finisher to slaughter. Cornish Cross can work on pasture, but slower-growing birds are another option if your customers prefer firmer meat and accept a longer growing period.

If selling, confirm the buyer’s preferred size and your processing route before placing chicks. Market and value-chain practice puts buyer requirements ahead of breed potential: extra growing time costs feed without necessarily earning a better price. The example plans five cycles a year; preserve time for cleaning and pasture recovery rather than treating market age as the whole cycle. Replace all supplied cost and sale-price planning figures with your own, and check applicable processing and direct-sale rules.
