It's great but be aware that
a) you need a GOOD energizer for it (it is a fairly heavy load), and
b) you need to either move it every few weeks during the growing season (to somewhere with shorter grass, or mow along where it goes) or spray Roundup etc along it as needed (personally I do not recommend this), as it doesn't take very much grass/weed growth at *all* to totally ground it out, and in fact it can get seriously stuck in place if you let lots of vegetation grow up into it.
Also in a windy location you will need extra reinforcing, like tying back to extra T or step-in posts.
I highly recommend Premier as a source (
www.premier1supplies.com) they have EXCELLENT products, service and good prices; I have no experience with
www.kencove.com but they do sell a similar product as well.
You can set it up fine with just one person, although 2 does make it a bit easier/faster.
About shade, unless you are in a cool-summer area and have only a couple chickens I would be really concerned about a plastic doghouse not being enough shade. You might need to construct a small moveable shelter - it would not have to be like a full enclosed tractor, just like what books or websites sometimes call a 'range shelter', sized down for your actual # chickens. You'd just have to make sure it would not leave during high winds.
Hope this helps,
Pat
