Watch yardsales, craigslists, check lowes and others for free offcuts of lumber, notice construction or repairs going on in your area especially now that weather is getting nice. Often they will be throwing away whatever they demolish. Ask if you can take whatever they toss. You might have to pick through but it's worth it. And be patient. I got my first 67 week old flockmates in November rather than spring so they could spend the winter growing (the time an adult wouldn't lay anyway) . By the time they hit laying age it was spring. If i had gotten spring birds they would have barely begun to lay and would have stopped for the winter. Work towards getting fall chicks which gives you more building time.
