Fig. 51. — No fences to interfere with cultivation or the liberty of the /owls 



will return to their own home to roost after becoming flocked. In order 

 to teach fowls to return to their own pens release them the first few times 

 late in the afternoon, leaving the partition doors open. Flocks of five 

 hundred to one thousand birds may be allowed to range together, having 

 much greater liberty and allowing easier cultivation of the field, greater 

 accessibility and economy of fences. Compare Figs. 51 and 52. Under 

 these conditions, a double-yard system can easily be practiced in order 

 to make possible the cropping and renovation of the land. Only under a 

 large double-yard system is it safe to house a large number of fowls on 

 the intensive plan, because of the easy contamination of the soil. Under 

 the one-yard method such contamination is very difficult to overcome.
