Are Jacob sheep actually black and white?

Not quite. While the patches are genetically black, they rarely stay that way—the wool weathers to a deep chocolate brown or lighter lilac tan over the season. So what looks black from a distance is usually brown up close.

How many horns do Jacob sheep have?

It depends—most commonly two or four. The four-horned variety is the breed's hallmark, with the top pair growing vertically (sometimes up to two feet) and the lower pair curling down along the side of the head.

How long do Jacob sheep live?

Exceptionally long for sheep—they're productive for 7–9 years commercially, but in smallholder or pet settings they frequently live 12–15 years. Some ewes have even lambed successfully at 16.
