Portable chicken coop/run tractor?

[blackswamp]

Is there such a thing is what I'm asking first? I want something that will house 4-6 chickens (10-16 weeks of age) that is predator safe & portable. When I'm not using it I want to be able to break it down some for storage.
So does anybody have plans or pictures or even build one? I also would like to put a set of wheels on the back to move it around the yard.

Thanks
Jeff

This may sound silly. I built one today though. Do a search on the Pinterest.com site. TONS of ideas. Hope this helps I know it's doable.
