You also can attach an awning from the front of the roof to provide more shade and protection. You also might want to install a grounded lightning rod, particularly with metal sheds, suggests Goble. This extra height provides a little head room in the event that one of the horses rears up. Make sure the shed is wide enough to accommodate safely the number and size of horses which will be using the shelter. Temperament of the horses also might be a factor.
Draft horses are a little more docile.
Generally, about 75 to 100 square feet per draft horse is within acceptable limits. If your horses will be getting feed and water in the shed, place an appropriate number of feed boxes and water troughs at the back. If several horses will be accommodated there, space feed boxes apart to reduce a dominant horse from getting the lion's share. Spread it around. Some experts, including Raymond, suggest using interior partitions in sheds.
