372 CARE OF THE GROWING STOCK 
peach orchard can be profitably maintained as a range area for 
the shade which can be derived. 
When no trees are present, or while the trees are getting 
their growth, it will be found profitable to plant such crops as 
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.

Fic. 172.—A desirable rotation of crops for poultry runs. Each year it is moved ahead 
one plat, the houses always being located on the wheat and rye. 
Housing.—In the design and construction of range or summer 
developing houses, there are three cssential 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-
