I think this could work if thought out properly. A 55 gallon rain water collection barrel with the nipple water system could provide enough water for them, and I personally have made an automatic feeder tht lasts my girls over a week. I would recommend an automatic door for the chicken coop too, just to offer more protection. There are some that run off of solar panels, so that cuts down on electricity costs. You may want to consider electic strands around the bottom of the fencing, just for more protection. You have 6 months to figure this out, so you have plenty of time to find the right setup for you.
