Thread Description:Looking for specific breeding boxes
I am not sure where to get them, you may need to take a picture and measurements to someone to build them for you. I do know several people who use these types of nest boxes, and they are very good. The ones I used to use are very similar (though I think being taller is better) and I far prefer them to the standard rectangular with concave ones.
