Do your goats need shelter but are not ready to put up your dream barn? If you have large round bales this is a great option. We place big round bales (over 1500 lbs) in a U shape and put a simple flat roof on the top built with 2 by 4's and Plywood. We seal the seams with all weather rubber sealant.
In our experience in Kansas these hay houses last about 2 yrs before needing to be replaced. The roof is removed with a tractor and loader with bale forks. Once the new bales in place the roof is put back on.
For growing kids these hay houses double as an exercise equipment.
