CROPPING SYSTEMS 415 



It is usually considered that about 7 sheep eat as much 

 as a cow. 



Well-fed hens eat a little more than twice as much for 

 their weight as do other farm animals. The common 

 estimate of a bushel of wheat or equivalent for a hen a 

 year is not far from correct. If only a few hens are kept, 

 a large part of this may be picked up around the farm.
