Ending the chicken reign of terror

We have long been unhappy with the liberties the chickens have taken in our yard: eaten all the flowers, digging up the grass, pooping everywhere....but lately it has gotten out of hand. Several of our neighbors have knocked on our door to tell us the chickens are in their gardens, one several houses down the street. But the tipping point was when Simon was in the backyard a few days ago and the guy behind us complained to him about chickens wrecking his yard. So, I went online to see what the world has to solve this problem. I found this (Simon comment: I love the trio of animals on the right - it looks like the cast of a Wonderful World of Disney adventure, where they all have to trek across America together):

It's a system of black metal panels, each 2' by 4'.  Every 8 panels there is a little hatchway.  You can get as many as you want to link them together.  Of course there are accessories as well, screen roof segments, canvas segments to block the sun...I got three wall units and three roof pieces and somehow ended up with 3 too few roof segments.  (I didn't take into account that, when you connect the 4'x4' sets together, you get more 4'.  So, more roo segments needed.

Here it is so far. I'll buy three more roof pieces and their cage will double.
