Iso of pics and designs large hen mobile or coop on trailer

[lefty26]

I am looking for help with designs or just pictures for a large coop on a a wagon or trailer.

I am wanting to build to rotate 100 to 200 layers on the farm they will spend all day outside and only come in to lay eggs and locked up at night.

I don't have any pictures but they are some local farms that have about the same size flocks and they use old school buses.
