Building a duck house or duck box provides nesting ducks with a safe place to hatch their young. Most duck houses for wood ducks are built over the water, which deters land predators such as snakes, raccoons and foxes. The houses allow ducklings a chance to grow larger and stronger before having to enter their land environment, and protect them from bad weather.
Measure and cut four pieces of plywood 6 inches by 12 inches. These are the sides, front and back wall of the duck house, and should be uniform in size.
Measure and cut one piece of plywood 6 inches by 6 inches. This will be the bottom or floor of the duck house.
Measure an cut one piece of plywood 8 inches by 8 inches. This will be the top of the duck house and needs to be larger than the floor panel to keep rain out of the entrance hole.
Drill or cut a hole that is no more than 3 inches by 4 inches into one of the 6 by 12 pieces. This is the entrance hole, and should be slightly higher than the centre of the piece.
Measure and cut a piece of chicken wire that extends from the entrance hole down to the end of the wood. This wire will be used by the ducklings like a ladder to climb out of the house.
Staple the wire to the wood. Make sure this side is on the inside when you assemble the house.
Drill a hole one inch below the entrance hole, and install the wooden dowel rod. This will be the perch for the duck to land on before it enters the house. The dowel rod should protrude two inches.
Nail the four 6 inch by 12 inch pieces to the 6 inch by 6 inch bottom piece.
Screw the 8 inch by 8 inch piece to the top of the house. Do not nail this piece, you want to be able to unscrew the top and clean out the house after each nesting.
Attach the mounting bracket to the back of the duck house. This will allow it to be installed on a pole above the water, or attached to a tree.
Shove a few cotton balls into the duck house. This will be used by the mother for nesting material.
Paint the duck house green or brown. This will help it blend in with its environment and attract less attention from predators.
