I made a mini swamp cooler for my chicken hospital. I'm getting a 25° drop from ambient, I could get it colder by fixing some air leaks but it's already at 75° supply, which is a bit cold. Trying to break a broody hen right now. This could also be used to cool a coop. Costs about $50-75 to make depending on size.
