Poultry manure is produced during the normal operation of hatcheries, broiler production and egg laying production. It also occurs in turkey and waterfowl production. Since a majority of poultry manure is produced in broiler and layer operations, special attention will be paid to these two specific parts of the poultry industry. There is a basic difference in the set-up of layer and broiler operations which leads to a difference in the type of litter produced. Caged systems are used mostly for laying operations but their use is growing in the broiler industry as well. In the laying systems, each cage contains 1-25 birds.
