Any chance you could make one about 10' by 12' .....I'll live in one! Just make like a huge garage door on one side so I can get in.
I'd use the birds for heat in the winter, the droppings I'd use for....I don't know.
But those are some amazing birdhouses.
The one you just pictured, how much is that one?
If you don't have a facebook group, you definitely need one to show to the masses. I just recently posted your link to many to show everyone the craftmanship.
