comming home to roost

I made these concrete S.U.V's a few years ago. Their linked together by a chain running through their internal selves. Their each about 4" long (10.16 cm) . Where I live many people drive these look-a-like vehicles. They are bloated and top heavy and there american.

They are all ready concidered obsolete and will be abandoned on mass. What can be done with these forms? My first thought is to gut them, recycle the plastic and make them into a suberban chicken coops. This smells like a bussness oppertunity! You could even get the kit that suits your make and model. If any one has an idea to share it would be fun to read.
