of Six Model Firms, and Supply Bands Added as Firm Size Increases, 



5,000 Pounds Per Square Mile Per Year Density Level. 



pound point in each supply band is shown in Table 1. For any work day 

 this is also the number of birds of market weight located anywhere in 

 the band, so specifies the maximum flock size that can exist in any par- 

 ticular band. 



This condition is relaxed somewhat by the assumption mentioned 

 earlier that a flock of one-aged birds can be as large as the quantity that 

 will be picked up from a given band in two days. So the maximum size 

 of flock allowed in terms of one age group of birds is: Band I - 9,600, 

 Band II - 19,200, Band III - 28,800, Band IV - 22,400, and Bands V and 

 VI - 40,000. These numbers also specify the maximum numlier of birds 

 of a given age group allowed in the whole of each band. With this desig- 

 nation of impound points no inband travel between farms is considered. 

 Assuming that there are 247 days during the year when poultry is assem- 

 bled and each farm produces five flocks per year, there will be about 50 

 possible impound locations in each band. 



The location of the impovmd point in each band bears a relation- 

 Bhip to the radius of the band. The impound point will be located in
