Large pigeon coop: 4' x 8'; 6' tall at sides and 7' tall at peek. Has nesting shelf. It's on some sort of pallet on wheels.
Needs work but amazingly has kept out invasive critters til recently when pigeons found new home.
You could come and see if it's something you are considering. No commitment necessary.
My neighbors with tractor have unearthed the bottom of this coop, albeit with much difficulty. We found 2 wheel axels without wheels that were buried, but it is now free to lift but not roll anywhere. There was an upright that cracked in the process. There is plenty room to get truck and flatbed into the space to pull it.
