A large, hardy long-wool breed developed on the wet Romney Marsh of Kent, England, prized worldwide for a heavy, lustrous fleece and its exceptional resistance to footrot and damp conditions. It is a foundation breed of the New Zealand sheep industry.

Minimum
Small flock dry-lot + shed
0.5 ac dry-lot for 4–5 head + 3-sided shed
Sheep are obligate herd animals — keep at least 2–3, never solo. A half-acre dry-lot with daily hay, fresh water, mineral access, and an open-front 3-sided shed for shade and weather. Perimeter must be predator-proof (sturdy woven wire or electric net).

Recommended
Rotational pasture
≈ 1 ac per 2–3 sheep, rotated paddocks
Rotate the flock across 2–4 paddocks to break parasite cycles and keep forage healthy. Provide a windbreak/shelter, free-choice minerals, clean water, and a guardian (LGD) or strong perimeter fencing against coyotes and dogs.

Ideal
Managed pasture + LGD
Managed rotation, LGD, full hoof/shear program
Large managed pasture rotation with a livestock guardian dog, scheduled hoof trimming, shearing once or twice a year, and parasite monitoring (FAMACHA). Lambing barn or jug space available in season. Romneys are a dual-purpose longwool breed adapted to wet pasture — they tolerate damp ground better than many breeds but still need dry shelter.
Life & growth stages

Newborn
Newborn mammals are nursed on their mother's milk. Many are born helpless — blind, deaf, and sparsely furred (altricial, as in dogs, cats, and rodents) — while others stand and follow within hours (precocial, as in hoofed livestock).

Juvenile
After weaning, juveniles grow quickly and become increasingly active, playful, and independent. Adult coat, proportions, and (in many species) the permanent teeth come in as they approach full size.

Adult
Adults reach full body size and sexual maturity, with the species' mature coat and build. Sexual dimorphism — differences in size, mane, horns, or markings — is pronounced in some mammals and subtle in others.
Senior
Senior animals show aging signs such as graying fur, reduced activity, and a greater need for veterinary monitoring of joints, teeth, and organ function. Lifespan and the onset of old age vary widely by species and size.
Color & pattern variants
Natural variants occur in the wild; selectively bred (man-made) variants were developed in captivity.
Thrives on open pasture, including wet, low-lying ground that would lame other breeds, thanks to its hardy feet. Provide secure fencing and a simple shelter for shade and lambing; the dense long fleece makes Romneys very weather-tolerant. Rotational grazing controls parasites. Ensure clean water and free-choice sheep minerals are always available.
Diet
Grass-based grazing is ideal — the breed is an efficient forager that does well on pasture alone in temperate climates, with hay in winter. Avoid over-rich feed and copper-supplemented cattle/goat rations (copper toxicity risk). Lactating ewes raising twins benefit from extra forage or modest concentrate. Provide constant access to fresh water and a salt/mineral source.
Behavior & temperament
Calm, quiet, hardy and self-reliant with good mothering instincts — easy to manage and well suited to extensive, low-input systems and beginners. Dual-purpose but especially a long-wool/fiber breed: the heavy, lustrous, crimpy fleece is a favorite of hand-spinners, and the breed also yields good meat. Foundational to large-scale grazing operations in New Zealand and elsewhere.
Health
Notably resistant to footrot and foot scald compared with most breeds, a major advantage in wet climates. The long fleece still requires management: shear at least annually and crutch to prevent flystrike, which is the main risk in heavy wool. Watch for internal parasites (FAMACHA), and select against wool over the face. Standard CDT vaccination and hoof checks recommended.
Tips, DIY & hacks
Shear once a year; the dense long-staple fleece is valuable, so handle and skirt it carefully for the hand-spinning market. Crutch and dag (remove soiled rear wool) regularly to deter flystrike in warm, wet weather. Their tolerance of damp ground makes them ideal for marshy or high-rainfall properties where other breeds get footrot. Gentle disposition suits novice keepers.
