Kreher’s Poultry Farm is a third generation family farm located in Clarence in Erie County, about 15 miles east of Buffalo, New York. The on-site composting system was initiated in 1995 with the first building, and a second building was added in October of 2000. The farm itself consists of a “laying complex” with six hen houses, housing approximately 600,000 hens, as well as a “pullet complex,” two buildings with 200,000 replacement hens. The manure from all of these houses is collected and transported to the two composting buildings using a conveyor belt system, with the exception of manure from the pullet houses and one of the laying houses, which is transported by truck. The compost is kept in long windrows and turned every three days, and slowly moved lengthwise down the building.
