There is a farm that raises game birds about 15 miles from me that would provide chicks, but I would still have problems with suburban neighbors calling the city and shutting it down. (People are tearing down homes around me and replacing them with expensive upscale housing.)
Ideas...A house. If you have a lot of timber...cedar or poplar Stackwood might be an inexpensive way to build. I saw an article in Harrowsmith magazine about a cordwood house in Wildrose that cost $1200 at the time. (about 1975) The house was about 1200 sq feet.

Not enough timber on my land to try that yet. I have a plan that I think will work, I just need to run it by the Building Inspector first.
I can get the frame for a metal carport fairly cheap. My plan is to start with that, wrap the outside in wire mesh, then cover the mesh with fabric that’s been soaked in concrete. A second layer of wire mesh/fabric/concrete on the inside of the frame, with a gap between the two layers of about 6 inches. Fill that gap with concrete that has insulative materials mixed in, and the result should be pretty solid.
I have different recipes for the concrete used in each layer, so the outer one would be waterproof and the inner one would be mold-retardant.
If things get bad before I get it finished, I know how to make concrete from natural materials. It’s a lot more work than just buying it in a bag, but it can be done.
