I've been really lucky to have many talented woodworking friends, who have donated time, knowledge, and scraps!
All of the nesting boxes are built from a combination of cedar and reclaimed wood. They all have a hatch that opens for easy cleaning.
My yard is filled with test houses, or houses that came out just a little too wonky to sell. It's been a joy watching them get put to use. Here's a gallery os some of my work. I'll go into detail more in future editions.
I sell them in my Etsy store. Have a look!
