I have family that manages a local grocery store. We can get near expired bags full of random produce, $2
I have fed chickens, myself, and gathered seeds for next to nothing. Check local grocers for daily clearance
What I'm wanting to do is use a high cfm fan disguised as an ac condenser. With duct going to ceiling to draw out hot air and positive air flow in through windows. I'm hoping to get a deal on closed cell foam insulation.
My goal is to make this like a mini house. I'm adding a garage to park mower and tools. I found a case for a/c condenser and I wand to place an exhaust fan inside and run ducts for ventilation. I have to remind myself it's for a chicken. Using what I have on hand and building it myself.
I just threw it together with ripped 2x4 and fence picket scraps. It was free. Building coop this weekend. A pole-barn style coop with solar and water.
