Pigeon Trap Door Dimensions | Best Trapping Systems for Racing Pigeons
Mark a 20-inch- by- 20-inch square at the top center of your pigeon shed. A 20-by-20 opening will provide a large enough passage for your pigeons to enter but not too large a space to protect with your trap door. Make your trap-door opening by cutting along your dimension marks with a skill saw.
