As a general rule, raising broilers in large commercial houses is the most efficient way to grow chickens. The houses are usually 40-50 feet wide and 400-600 feet long. Most often, a commercial chicken house contains about 20,000 birds. Using these houses, it’s not difficult to manage every part of a broiler's life so they grow at optimal speed.

For commercial production, the better dimensions of your broiler poultry housing will be 40 to 50 ft wide, 400 to 600 ft long with about 8 ft sidewalls. Although, the dimension may vary depending on the number of birds and your production purpose.
