In the Summer of 1977, after moving into our present home, I found something in the rafters of our detached garage, that looked like a flying saucer! It turned out to be a chicken brooder. We also had a 50 ft chicken coop, with half the roof caved in by the previous Winter's heavy snows. We ended up tearing down the coop. It seems odd now, but I can't remember how we disposed of the UFO.

It was around 5 ft in diameter, and had a 1/2 inch pipe for gas or propane. I did find later, an old 1 1/4 pipe that I suspected came from an old gas well.? The house was built in 1919, so I'm not sure when it was in use. Being from the city, it was kind of like a "Green Acres" experience.
This is not the one, but similar.
