Sheep's wide-set eyes give nearly panoramic vision, but their depth perception in the zone directly ahead of them is poor. Things right in front of them can be harder to judge.

In heavily wooled breeds, fleece that grows too long over the eyes blocks the sheep's vision completely. Farmers call it wool blindness and have to trim it back before the sheep walk into things.

Sheep can spend up to eight hours a day just chewing. They graze in daytime and chew cud in the evening, lying down and looking extremely peaceful.

Rotational grazing moves sheep between pastures on a schedule so grass can recover between visits. Sheep left in one spot will destroy it.

The oldest, most experienced ewes in a flock know where the best grazing is, where water can be found, and where shelter is. When a flock loses its eldest sheep, the whole group can lose that knowledge with her.

In mixed flocks, goats wander off on their own while sheep stay grouped together. Goats are, without question, the troublemakers.

Sheep establish social rank partly through head butting. Rams are especially serious about settling this.

Crowding at feeding time makes sheep competitive and stressed. Give them more space and the pushing stops almost immediately.

Sheep are used in targeted grazing programs to control invasive plants. They eat the problem vegetation repeatedly until it gives up.

Sheep accumulate copper in their livers and can die from copper toxicity at doses that are harmless to goats. It catches a lot of farmers off guard.

Wool is graded after shearing by fiber diameter, staple length, and contamination level. The sorting process is meticulous and matters a lot for pricing.

Hundreds of traditional sheep breeds are at risk of extinction because industrial farming favors a small number of high-output breeds.

Ram skulls have internal air pockets that cushion impact during head butting. The bones are also thicker and differently structured than ewe skulls. They hit hard enough to need the protection.

Sheep have almost no sweat glands. They regulate temperature by panting instead, and on very hot days they can overheat quickly, especially under a full fleece.

A sheep's normal body temperature sits between 102 and 104 degrees Fahrenheit. They run hotter than humans, which is notable given the built-in wool blanket.

Sheep saliva contains compounds that stimulate grass to regrow after grazing. They're not just eating the field; they're chemically encouraging it to recover.

Sheep milk contains about twice the fat and protein of cow milk. A small amount packs a lot in, which is why sheep milk cheeses tend to be so rich.

Wool biodegrades in soil and releases nitrogen and other nutrients as it breaks down. Some gardeners use raw fleece as slow-release fertilizer.

In 2020, a Texel ram named Double Diamond sold at auction in Scotland for the equivalent of about $490,000. The buyers believed his genetics were worth it.

Wool retains about 80% of its insulating ability when soaked through. Cotton loses almost all of its insulation when wet, which is why experienced outdoors people avoid cotton in cold weather.

Wool grows in natural clusters called locks. The curl pattern within each lock determines how the fiber behaves when spun.

During the same era as the famous cattle drives, millions of sheep were moved across the American West on trails stretching hundreds of miles. The shepherds, often Basque immigrants, are mostly forgotten.

A sheep's rumen, the first of its four stomach chambers, contains billions of microbes that ferment plant material. Without them, the sheep couldn't extract any nutrition from grass at all. Every sheep is basically a tiny ecosystem.

Sheep in the same flock often sync their daily rhythms without any visible signal between them. They tend to graze, rest, and chew cud at roughly the same time, even when scattered across a large field.
