Southdown housing needs remain relatively straightforward, requiring basic shelter from precipitation, wind, and summer sun without demanding elaborate barns or climate control. A three-sided structure or simple barn providing approximately 15-20 square feet per adult sheep for resting, feeding, and lambing areas suffices in most climates. The shelter need not be insulated but should keep sheep dry and block prevailing winter winds while maintaining good ventilation to prevent respiratory problems. Southdowns' dense wool provides excellent cold weather insulation, but wool that becomes wet loses insulating properties, making dry shelter important during winter precipitation.
Good ventilation in housing areas prevents the buildup of ammonia from urine and reduces respiratory disease risks without creating drafts directly on resting sheep. Many successful operations use open-front barns or pole barns with roof coverage but no walls on the lee side, providing weather protection while maintaining air movement. Enclosed barns require sufficient ventilation openings placed to move air without creating floor-level drafts. Poor ventilation contributes significantly to pneumonia and respiratory infections that affect flock health and productivity.
Fencing for Southdowns must prevent both escape and predator entry, with specific requirements depending on local predator pressure and whether guardian animals are used. Woven wire field fence with small mesh openings (4 inches or less), standing 4 feet tall, provides secure perimeter fencing when properly braced and tensioned. Electric fencing also works well, particularly for subdivision within secure perimeters. Southdowns' calm temperament and moderate size make them less likely than larger, more active breeds to challenge fencing, but secure barriers remain essential for both containing sheep and excluding threats.
Predator protection requires serious planning, as sheep face persistent threats from coyotes, domestic dogs, bears, and other predators varying by region. Even small flocks can attract predators, and a single successful attack often leads to repeated predation that devastates flocks economically and emotionally. Secure fencing forms primary defense, supplemented by livestock guardian dogs, donkeys, or llamas in higher-risk areas. Some small operations house sheep in predator-proof barns nightly, particularly during lambing when vulnerable newborns attract extra predator attention.
Rotational grazing benefits Southdown operations significantly by improving both pasture productivity and parasite management. This management system involves dividing pastures into smaller paddocks and rotating sheep through the sequence, allowing pasture rest and regrowth between grazing periods. Rotation also interrupts parasite life cycles by moving sheep away from contaminated ground before infective larvae develop fully. Paddock size and rotation frequency depend on flock size, forage growth rates, and season, but generally sheep should move every 3-7 days during active growth, with paddocks resting 30-45 days before regrazing.
Water availability throughout the year remains non-negotiable, with adult sheep requiring 1-2 gallons daily depending on temperature, forage moisture, and lactation status. Clean, fresh water must be continuously accessible. Automatic waterers simplify management in permanent facilities, while portable tanks serve pasture rotations. Winter water in freezing climates requires heated waterers or multiple daily ice-breaking. Water quality and cleanliness directly affect sheep health and productivity - contaminated or stale water reduces consumption, limiting feed intake and performance.
Handling facilities enhance safety and efficiency for routine care, health procedures, and sorting. Basic requirements include a small catch pen where sheep can be gathered, a narrow chute or race allowing individual restraint, and possibly a loading ramp for trailer access. These need not be expensive or elaborate - many shepherds construct portable panels that configure various ways for different tasks. Utilizing the breed's calm temperament and following behavior allows efficient movement through handling facilities with minimal stress.
