Sketch of Swallow Bird House P APP
One of the Swallow building designs that many Walet farmers like is the design of the Swallow house model zigzag. This house can be used in all sizes, including 4 x 8, 5 x10 and 5 x 12.
The difference is that in the interior or part of the Swallow house there is a VOID (plunge hole) in the shape of a zigzag. That is, the hole that became the bird's flyway Swallow between floors made zigzag, not straight from bottom to top
