Look into the KATAHDIN breed of sheep. We have been raising these for over 6 years. They are a hair sheep that require no shearing. Easy to maintain, easy on fences. They are heat tolerant, too. Good breeders, usually having multiples after first birthing.
You are welcome. The Katahdins are being used by many areas to control brush along easements. My sister first brought this breed to my attention through articles in the Smithsonian and National Geographic magazines.
There are a lot of people raising these.
