A few thoughts on the water situation: Paint the water container black for sunny days, make sure the chickens have access to snow if you have it (they will eat snow as a source of water), bring the waterer in at night to thaw then return to chickens in the morning (I do this now).here is one solution for shelter.

I think I will have one nest box mounted outside for each hen inside.
The Natural Chicken keeping thread on this site mentions using golf balls to force broodiness in hens, that is why I will need so many nests.
Hardwear Cloth to keep out racoon's paws.
I will be able to move this to fresh grass daily and in that way have less need for medication.
I must think of a way to keep coyote(s) from digging in and yet still have it portable.
The temperature in Kansas City area is below 10 degrees F in January so keeping water liquid without electricity will be a challenge, please give me your thoughts.
Great thread btw, I'm also working toward self-sufficiency.
