We raise them.
Here is what I think about them. Others may have different views. DH is asleep, otherwise I would have him tell me his words to type. The Jacobs are his project that he has been working with for over 20 years.
We are having to start over, because coyotes killed around 28 of them a few years ago...leaving him with 1 ram and 1 ewe. We found 1 purebred ewe we liked and purchased her. We have been cross-breeding for now, until we find more ewes that we want.
That is what prompted us to get Great Pyrenees dogs. DH had one, but he died of old age...his presence had a lasting effect on predators, they didn't come back until old Jake was gone for a couple of years.
Ours have 4 horns, unless we cross them with another breed, then we get 5, 6 or more horns. When they have that many, the horns sometimes grow together or a horn will split, making it not as sturdy and apt to break off.
The horns are very soft for a long time. You need to make sure they aren't in herd situations that the young rams will get knocked around and get their horns broken.
They are lighter and take longer to mature than most meat breeds, though they are good to eat.
The rams make fantastic trophy heads.
They are a lot lower maintenance and hardier than modern sheep. This breed has not been "improved" by man like other breeds of sheep for production purposes. This is why you don't see them everywhere, they aren't economical for large producers.
We love ours!! When other sheep owners were doctoring, seemingly constant for hoof rot, worms, pinkeye, ringworm, and calling us for help with lambing troubles ...our Jacobs were fat and sassy, no hoof problems, no lambing problems, no pinkeye, etc.
I have a few Dorper sheep too, and they require more feed and care than the Jacob's.
Got to love what Mother Nature creates and man doesn't mess with!!!! We think they are a great breed!
