An important feature of the range shelter described in this circular is that it is portable. Two men by inserting 2x4s through the holes located just below the roost supports and next to the center uprights can easily pick up and move it from one location to another. Frequent moving of the shelter prevents excessive accumulation of droppings in its vicinity which are a menace to the health of the birds. Better use will be made by the birds of the natural green feed produced on the range if the houses are moved often.
