Nice pens! They are similar to the ones we just finished building for our Modern Game!
I don't have any photos of the completed project yet but here is one of the progress shots that I took!

The pens will stay up on the metal stand so that they are raised off the ground. We put a plywood divider down the middle so it is 2 separate pens. Dimensions of each pen are approx 4.5' L X 2' W - which look plenty big enough for a trio of such small birds! We have a lot of ground space so we won't build ours on top of each other. We popped a laserlite (clear plastic) roof on top and boarded up half of the back to make a warm corner.
