I used three smaller pallets as the base make a U formation I used L brackets to keep them together. I then took two larger pallets and by using a large hinge connected the two. The hinge allowed me to adjust the fit to align with the top of the U. I did need help to lift the heavier large pallets and place them on the lower U. I then used scraps of metal flashing, and some scrap plywood to finish the outside. The goats loved it. But sadly we can’t have animals right now for health reasons.
