(Salem, OR) -- The Oregon Department of Agriculture has approved a permit for a massive chicken farm in Linn County. J-S Ranch plans to build a facility that can raise over 580-thousand broiler chickens, which means they're sold for food. The permit has been reviewed, with public comments, over two years. The facility can't leak waste or feed into the ground. Drinking water wells will be tested on a regular basis for contamination. ODA will monitor construction to make sure they follow requirements of the permit.
