The short answer for an adult Jacob
An adult Jacob needs forage in front of her for most of the day, not a tally of meals. A Jacob is a small, hardy, multi-horned sheep that browses bramble edges and weeds as happily as she grazes grass, and her digestion is built for that slow, varied intake followed by cud-chewing rest. On pasture or hay alone most adult Jacobs need no bucket feed at all in ordinary condition, and when you do offer a little extra, once a day is plenty for maintenance, with a morning and evening split reserved for thin, nursing, or winter-stressed animals.
A primitive breed with a thrifty stomach
The Jacob's background as an unimproved, self-reliant breed shows directly in how she should be fed. She converts rough forage efficiently, keeps condition on ground that would leave a larger commercial ewe hungry, and is prone to getting over-fat on rich pasture plus daily bucket feed, which brings its own lambing and foot troubles. Her browsing habit also means a Jacob flock uses a field differently across the day, stripping leaves, nibbling hedgerow shoots, then grazing, so the field itself provides the variety that owners sometimes try to add with extra servings. Steady forage and quiet rumination, not frequent feeding events, keep a Jacob's rumen settled.
A Jacob day that runs on forage and one good look
Let the flock range the pasture from morning turnout, and time your main check for when a small feed call, if you use one, brings every Jacob to the fence where horns, eyes, and gait are easy to see. In winter, spread hay in more piles than there are sheep so a shy Jacob is not shouldered away by bolder flockmates, and replace what is trampled rather than expecting her to eat soiled hay. Keep fresh water and sheep-suitable mineral available continuously rather than offering them at a set feed time. If a particular ewe is nursing twins or dropping condition, pen her briefly for her own extra serving instead of raising the whole flock's ration, because the rest of the Jacobs almost certainly do not need it.
Reading appetite and condition in a Jacob flock
Feel body condition under the Jacob's fleece at the loin, because that spotted wool hides both thinness and fatness from a distance. A Jacob who does not come to a feed call she normally answers, who chews no cud while the flock rests, or who isolates herself near the hedge should be caught and examined, and persistent loss of appetite in a sheep is a reason to involve a veterinarian quickly. Watch feet after wet spells at a muddy hay station, since lameness changes how far a ewe will walk to graze and quietly cuts her intake. Sudden access to a large amount of rich feed after a forage-only routine can also make a Jacob seriously unwell, so introduce any extra gradually over several days.
