When no trees are present, or while the trees are getting

 corn, sunflowers, and, if there are fences, flowering beans may be 

 grown. A good plan for rotation of crops is shown in figure 172. 



Artificial shelters may be made of muslin frames or branches 

 of trees supported a few feet above the ground.

Housing. In the design and construction of range or summer 

 developing houses, there are three essential features to consider, 

 namely, portability, fresh air, and size. 



The houses should be moved from place to place as the range 

 is changed. They may be used during the winter as laying houses 

 for small flocks. They should be so constructed as to provide an 

 abundance of ventilation and fresh air to the growing chicks 

 (Fig. 173). Crowded, stuffy quarters will weaken the vitality of 

 the chicks. When providing this ventilation, drafts across the 

 roosts must be avoided. It is a mistake to build colony houses 

 too small. Such a house is hard to ventilate properly, and the 

 tendency is to crowd too many chicks into one flock, with disas-
