I might think of something else to add later but for now I just want to second having a plan for fences BEFORE you actually have anything on the ground! Moving fence is so much work and life is so much easier if you only have to do it once. Think of how you want to connect pastures, where you want to be able to walk through, and where you may need access for a truck and trailer, how to get to barn/shelter from each pasture, etc.
