If you get a chance for a lot more pallets their is ways to make large pens with just pallets and screws that will hold goats. I even have 600+ lb hogs in pallet pens when high tensile electric won't hold them. I wrote 2 articles on how i build them with just the pallets and screws so it is super cheap. Same builds work great for birthing pens or quarantines also. This pen has been up over 5 years and I am just getting ready to take the top row off and reinforce the bottom to add hogs instead of goats. Nice article though it is always nice to be able to build something for mostly free.
