Live stock, poultry, rabbit or dog trailer - $500 (Marlow)

I was told this was a poultry transport trailer.
It could be used to transport any animal, bird, etc, that will fit in the compartments.
Dog hunting trailer maybe? Portable hen house? It's 12ft long, 7' 6" wide and 43 inches tall.
Takes 2 inch ball.
It has some rust as seen in the pics, but would make a good transport or movable cage trailer.
$500 cash in person, no trades, located in Marlow, OK.
