tion process, labor costs decrease from 1.168 cents per chick for hatchery 

 A to 0.386 cents per chick for hatchery H. Most of the labor economies 

 occur between hatcheries A and E. 



Investment and Costs for Building and Equipment 



Building Investment 



The size and layout that would minimize construction costs and pro- 

 vide a satisfactory arrangement for scheduling and performing opera- 

 tions was determined by analysing space requirements for various makes 

 of equipment, numbers of hatches per week, and types of work patterns. 

 Space for inventory storage of such items as chick boxes, pads, and feed- 

 er trays was standardized at a supply level sufficient for 30 days opera- 

 tion at 100 percent of capacity. Egg storage was standardized to hold 

 the maximum quantity required for the next scheduled egg setting. Space 

 for debeaking and vaccination was not added since these operations 

 are incorporated into existing aisle space or in the general work area. 

 The buildings were designed for a specific capacity but with no consider- 

 ation for future expansion. 



Table 6 shows the constructed floor space requirements for the eight 

 hatcheries. Square footage does not increase proportionately with the 

 increase in capacity. Certain areas such as the office, boiler room, and 

 rest rooms are not directly related to capacity and increase in size at a 

 slower rate. Increasing the nvimber of hatches each week increases the 

 frequency of vise of space for egg storage, general work area, and tray 

 washing. Consequently, only nominal increases in space are required for 

 these three areas for those models involved in this adjustment. An index 

 of changing space requirements with increases in scale, is the egg capa- 

 city per square foot of floor space shown in table 6. Egg capacity per 

 square foot increases from 76 for hatchery A to 129 for hatchery H. 



The buildings are assumed to he single story, concrete block struc- 

 tures on a concrete slab. All buildings are designed to provide room for 

 the same facilities except for hatcheries A and B which have the load- 

 ing area combined with the general work area. Each building is essen- 

 tially square to facilitate a circular work flow.
