Thanks all for the input! Lots of good ideas here.

Hmmm.... like for example... Phoenix? :) Yes, I do live in such an area. But on the other hand I would do this in the spring when the grass is growing, which also means we would be watering it every few days, which I assume would mitigate this issue.
You could also have a little box or something inside the tractor for them to sleep in at night that you can change the bedding in, that way the night droppings are not in your yard. You would just have to move the box in the daytime too.
This sounds like a very good idea. I could just collect and add them to my compost like I am doing with the droppings from my hens in the coop.
Free ranging would be much easier though, and while some say it slows down growth, it will still be way faster than a regular chicken, the birds will be healthier, and they will eat a bit less feed. You cannot expect a Cornish x to get much out of forage unless you do not feed them.
Truly free ranging wouldn't work for me - the poor things would get herded to death by my border collies. :) Also my husband is skeptical enough of this project - if they start hanging out and pooping on the patio they won't make it the whole 6-8 weeks, lol.
