And someday, when we have coops full of rescue chickens, we'll have rescue goats running and playing on their goat fort. /LOL you need a couple thick poles with a 2x6 going across from one to the other. Goats really enjoy that. Telephone poles work real well too.
snowshoe acres loves this simple goat shelter with resting bench. Build a resting bench with enough room for Your goats to walk underneath & lay down in deep warm bedding. Bedded 'den' areas under benches or inside study open sided wooden boxes will help trap body heat for warmth during extreme cold winter temperatures.
