The objective of this study is to provide hatchery managers and owners with in-plant efficiency and cost information on egg-type chick hatcheries. Hatchery managers can use this report to compare their in-plant costs and operations with those in the study and those synthesized in the models. Three major areas for comparison are (1) utilization of incubator capacities, (2) scheduling of work crews, and (3) use of laborsaving and cost-reducing equipment. Hatcheries may be able to reduce in-plant costs and increase their efficiency of operation by utilizing some of the methods used in the six model hatcheries.
