If you got a small farm or simply a plan of water and would love to keep Mallard ducks around, they are going to need a place to be protected from predators and you are going to need plans to build a Mallard bird house. Here is a simple idea to help you building a great house of their own and to provide them with the peaceful environment they need to nest and reproduce.
Build a Floating Platform
Protecting the ducks from predators is the main goal of building them a nesting house. Raccoons love to eat the eggs and they will find ways to get them. If you have a pond, a floating house is a great option to provide them a save place to nest.
Use a sheet of thick styrofoam and cut it in a half. This will be great to keep the nesting house floating. Join the two pieces of styrofoam together with 2 pieces of 2×4 or simple boards, leaving a space in between them. Once you have a solid foundation for the floating house, build a platform over the styrofoam with wood boards. Make sure not to use pressure treated wood, which is bad for the environment.
Build a House to Put on Top
It will be much better not to have the duck house sitting right on top of the platform. The Mallard house needs to be elevated a little, this is good for a floating house as well as a house on solid ground. This is necessary to protect the nest from getting wet from the rain and the possible waves of water coming on the platform on windy days. For houses on the ground, the possible variations of water elevation in the pound may flood the duck house after a big rain storm so you need to keep that in mind.
How to Make The Nest
To build a nest for the ducks, get a piece of plastic covered fencing that has about tree feet high by 5 feet long. Cover it with some straw hay and roll it like a cylinder of about 12 to 15 inches. Roll it completely and attach to fence together to make it stay tight. Thigh wraps will do the trick. Install the nest on the floating platform giving it an elevation of about twelve to fifteen inches.
You can do that by installing two pieces of wood across the platform. Them build a roof by using two pieces of plywood and installing them on the top of the nest forming a triangle shape all the way to the platform. Make sure the roof is longer than the nesting tube to provide protection at the entrance and the exit of the tube. This is a very basic design but that will make the Mallards happy and a will be a safe place to lay their eggs.
