 greatest item in the cost of production, — feed being first. 



Feed Wagons. — On large plants where the attendant makes 

 his rounds and must cover considerable distance, it is found very- 

 feasible to do the feeding from a wagon constructed for the purpose 

 (Fig. 119). This wagon may contain egg cases for the collection 

 of eggs, and a box or receptacle for the removal of droppings when 

 the houses are cleaned. Such a wagon is also useful for the trans-

 these are of several kinds: Protein, carbohydrates, and fat. The
