Nest Boxes Buitt or LumBer. 
This shows the front of the nest boxes as they face the interior of the squab house. They 
are from ten to twelve inches square, and the same distance deep. A slight variation does not 
matter. The fronts of the nest boxes are perfectly plain, as shown. It is not necessary to nail 
up pieces of board to keep the nappies and squabs from falling out. They will not fall out. 
The backs of the nest boxes may be on hinges, and be approached from a passageway, as shown 
in the picture on page 20. Or the backs may be solid, in which case you will get at the nesta 
by going into the interior of the squab house.
