per day by the 43 contract growers during the second phase. There is 

 niuch less dispersion about the logarithmic regression than in the first 

 phase, indicating less variation in management and/or technology. How- 

 ever, the number of man-hours expended per day per broiler decreased 

 with increases in flock size. There is no doubt that a family unit could 

 produce at a level of 35,000 broilers per flock, or that it could produce 

 on a still bigger scale if the first phase did not tend to be a restriction. 



Table 4 shows for the second phase the average number of man-hours 

 expended on different chores by growers in different size ranges. The 

 proportion of time spent on feeding remained relatively constant as flock 

 size increased, taking almost two-thirds of the labor input. Watering re- 

 quired a rather erratic proportion of the total man-hours with increased 

 size, although the proportion of man-hours tended to increase. The pro- 

 portion of time spent on other chores tended to decrease with increased 

 size. 



These analyses indicate two specific areas open to changes in tech- 

 nology to reduce labor requirements. Growers have indicated a desire to
