Thanks.  I have been checking out both of these suppliers but neither has what I'm looking for.  Have been looking at all kinds of reviews and got excited about this Australian company's coops before realizing they apparently only ship within that country.  I may revert to what I did for my first small coop.  I bought a wooden doghouse, added a door and 4" diameter holes on either end covered in hardware cloth, and put it up on cinder blocks.  It held up for a few years.  I just retired (I was a zookeeper working with birds for 22 years) and I really don't feel like building something.  Right now am waiting for a reply from the Australian company itself.  Thanks for your suggestion.  Maybe I'll end up getting a doghouse from Tractor Supply-there's one nearby.
