yeah that would be pretty small, but now with most things out of the way, and an actual design, I can probably get started during winter break, or maybe before if we have enough time during the weekends and if I get the loan sometime soon.
This picture is similar to what i plan on doing for our sheep and pig pastures and then put painted OSB sheets over it for winter. Since your in Montana @Finge make sure whatever shelter you build is a good wind break and faces the proper direction, which should be open side/door facing south or southeast.
