It's metal? Where are you located? Metal sheds are cold in winter, and hot in summer. They are very loud in the rain. You also have no windows if you need to lock your goats in.
Is it metal? It looks like it will need more ventilation. Another thing to consider is that if the roof is metal, warm air from the body heat of the goats will rise, condense on the cold surface, and rain back down in water droplets. I think you can find some insulating material you can spray on the underside of the ceiling to take care of this problem.
