Leftover chinchilla cages from a 5,000 animal herd. There were two barns full of these stacked 8-10 deep up against the wall. There are over 1000 cages in this photo.
Timers for the lights in one of the buildings.
Old style holding cage. This one is probably more than 50 years old, they tend to get recycled from breeder to breeder.
Wooden pine cage. Good for indoor chins, they keep the shavings in better than the wire ones.
