Last night I was watching The Antique's Road Show on PBS channel and someone had a pot that had a hole in the side and when I saw it I had the idea of using pottery as bird houses.
I don't personally want any but I thought it was a good enough idea I wanted to share it.
You could find someone who does welding to build a stand to fit the shape of the pot or just put it in a tree.
The pots with lids could enable you to clean it out or add straw for the next years birds.
If you have pots with handles they can be hung from high branches where cats can't get at them.
Someone might have already thought of this idea but I didn't want to spend a lot of time looking through old posts.
