Houses can only be built on paved land it seems (I've yet to be able to build them off of it, so plow/pave).
You'll need a lot more than 8 Exploration to find rustroot, I believe it's PER*EXP >= 400

Here.Chickens are simply picked up and put in a chicken coop (you CAN temporarily put them in a cupboard but they will die because they cannot eat outside of a coop.

Water
Sand
Clay (preferably of a decent quality)
Trees
Grassland
Soil (preferably of a decent quality)
