I love black and white photos, but quality color photos can be amazing too. Like some of them on here the picture detail is so sharp and clean. I am looking into the pallet option too, just because someone has access to 9 pallets for free. Wood is pricey and the cheaper I can get it the better. I did see on here under the coops page somewhere that someone did just that. Used the pallets as the walls and put plywood over it, and then used the gap in the plywood for adding insulation and then plywood inside so they didn't peck at the insulation. I can't imagine how heavy that would be. But it looked good when they were done.
I don't think I need to worry about insulation, do I? "Redding's coldest month is December when the average temperature overnight is 35.0°F. In July, the warmest month, the average day time temperature rises to 98.5°F."
