Birdhouse Building good business?

I've been wanting to get into birdhouse building for a long time, but I've been discouraged by some people who think it won't pay as much. Then I saw some articles where this filipino guy became a millionaire by just building birdhouses. I think it depends on the people, but I just want a simple, stable job working from home. Is it a good business?

Edit: I build birdhouses as a hobby and love it very much and birds love nesting in them.
