Like all horses though, they need shelter available in inclimate weather. A barn or three sided shelter works great as a wind break. They should be fed quality grass or mixed hay with fresh water always available. Grain can also be fed but they do not need large amounts. Like all horses they need regular worming, vaccinations and hoof care.
Curlies deserve the best of care and thrive under good conditions.
Good basic horse care applies to all breeds, even Curlies. In the spring when they start to shed, a brush, shedding blade or comb works great to remove the shedding curls. You can keep the shedded hair and spin it into yarn or find a spinner in your area that maybe interested in exotic fiber.
