I don't have a picture but I am currently making one out of a plastic storage shelf. 2 Bantams really don't need much space. It's a new experience for me too.
So far I have a added a roosting bar, I'm just going to line the outside with cardboard and hardware cloth as it will stay dry.
The simplest setup I have seen was a bike cage with a water jug with the top cut off as a nesting box filled with sand. Branch as a roost, job done. Depends how cold it gets, that would not be sufficient for mine but I think my converted storage shelf should work nicely, won't look very good but it won't cost an arm and a leg either.
