Divide the ground into pieces you can actually move
Rotational grazing starts with subdivision, and for goats and sheep the practical tool is portable electric netting or reels of temporary polywire on step-in posts, because the layout changes as the seasons do. Work out a rough circuit of sections sized so the flock clears one in a few days — small sections grazed briefly and evenly recover far better than a large field grazed patchily for weeks. Plan the practicalities as you divide: a lane or a sequence that lets you shift the flock without a rodeo, water that either moves with them or is reachable from every section, and shade or shelter in each piece, because a section without shelter is a section they cannot use in bad weather.
Move on the grass, not the calendar
The signal to move is the sward, not a date. Move the flock when the section is grazed down evenly but before it is scalped to the crowns — leaving a few inches of leaf lets the grass regrow from its own reserves instead of its roots. Goats and sheep graze differently and it shows in a rotation: goats browse upward, taking weeds, leaves and the tops of coarse growth that sheep ignore, while sheep graze low and close like mowers. Running them together or in sequence — sheep following goats through a section, or the other way round — uses the whole sward and neither species is forced onto the growth it likes least.
The rest period does the real work
What makes rotation more than just moving fences is the rest each section gets afterwards, ideally several weeks and longer in warm, wet weather. Rested grass rebuilds root reserves and comes back thicker, and the break matters just as much below ground level for worms: eggs passed in droppings hatch into larvae that climb the grass to be eaten, but most die if no animal returns for long enough, so a good rest genuinely lowers the worm burden your flock picks up. Top or mow a rested section if it has grown rank and stemmy before animals come back to it, and harrow droppings in dry weather to break them down.
Water, minerals and shelter travel with the flock
A rotation fails on logistics: if moving the water is a half-hour ordeal, moves get skipped and sections get overgrazed. Use a trough you can tow or carry, or run a pipe with quick connectors to each section. Keep the flock's mineral lick in the current section — sheep must have sheep minerals, because mixes made for goats or cattle contain copper at levels sheep cannot tolerate — and move the field shelter or choose sections with natural shelter in turn. Check the electric netting daily while they are on it; goats in particular treat a flat battery as an invitation.
A rotation only works if everyone moves the flock the same way, so keep the plan in KinsLe's Family Sharing — the section order, the last move date and which piece is next sit in the flock's shared details, and whoever is on the yard that day moves them onto the right grass rather than the nearest.
