7 Sheep Winter Care Essentials That Prevent Common Issues

The first cold snap isn’t the time to start thinking about winter sheep care; by then, you’re already behind. A successful, low-stress winter with your flock is built on proactive steps taken in the fall. The goal is to prevent problems, not just react to emergencies when the wind is howling and the water troughs are frozen solid.

Proactive Planning for a Healthy Winter Flock

Winter problems rarely start in winter. They begin with a lack of preparation in the fall, when the weather is still mild and the ground isn’t frozen. This is the time to walk your property with a critical eye, thinking not about how things are now, but how they will function in a snowstorm or a week of sub-zero temperatures.

Your checklist should be practical and tangible. Do you have enough hay secured to last until spring, plus a buffer? Are your mineral feeders full and protected from the elements? Take inventory of essential health supplies like dewormers, wound care sprays, and electrolytes before an emergency forces a trip to the farm store in a blizzard.

This is also the moment to assess your infrastructure. Check your fencing for weak spots that could fail under a snow load, and ensure gates can swing freely even with a few inches of accumulation. Look at your water setup and shelter with an eye for winter’s specific challenges. A small repair in October can prevent a major failure in January.

Providing Three-Sided Wind and Moisture Breaks

Many new shepherds overthink shelter, assuming sheep need a cozy, enclosed barn. The truth is, a full fleece is incredible insulation, and sheep are far more tolerant of cold than they are of being wet and drafty. The primary goal of winter shelter is to keep them dry and out of the wind.

A simple three-sided structure, or lean-to, is often the perfect solution. It blocks the prevailing wind and keeps rain or snow off their backs while allowing for ample ventilation. Poorly ventilated, closed-up barns can trap ammonia and moisture, leading to respiratory issues that are far more dangerous than the cold itself. The open side should face away from your typical winter winds, often south or east.

Don’t get hung up on building a perfect barn. Effective windbreaks can be created from what you have. A dense stand of pine trees, a solid board fence, or even large round bales stacked strategically can provide the necessary protection. The key is giving them a place to get out of the elements and stay dry, allowing their wool to do its job.

Ensuring Constant Access to Unfrozen Water Sources

Water is the most critical nutrient for sheep in winter, yet it’s the first one to become a major chore. Dehydration is a serious risk, leading to decreased feed intake, impaction, and problems for pregnant ewes. Sheep simply won’t eat enough snow to meet their needs, and they’ll drink far less from a trough with a skim of ice.

For a small flock, heated water buckets can be a lifesaver, though they require running power safely. For larger groups, a submersible stock tank de-icer is a worthwhile investment that pays for itself in labor and peace of mind. These devices don’t boil the water; they just keep it from freezing over, ensuring your flock can drink freely anytime.

If electricity isn’t an option, you must commit to the reality of hauling water. This means breaking ice and providing fresh, lukewarm water at least twice a day, and more often in extreme cold. It’s a demanding, non-negotiable task. Relying on sheep to break through ice themselves is a recipe for chronic dehydration and a cascade of health issues.

Increasing Hay Quality for Higher Caloric Intake

The simple act of staying warm burns an enormous number of calories. As pasture quality plummets and snow covers the ground, your flock becomes entirely dependent on you for their energy needs. This is where the quality of your hay becomes more important than ever.

It’s a common mistake to think any hay will do as long as their bellies are full. A lower-quality, stemmy first-cut hay might suffice in milder weather, but it won’t provide the caloric density needed in deep winter. The digestive process itself generates heat, and a higher-quality, leafier hay (like a good second-cut alfalfa or grass mix) is more digestible and packs more energy per pound. You are feeding them to fuel their internal furnace.

This is especially critical for ewes in late gestation, as their nutritional needs skyrocket. Waiting until you see sheep losing weight is too late. Plan to transition to your best-quality hay as the weather turns consistently cold, and provide it free-choice so they can eat whenever they need to.

Conducting Regular Body Condition Score Checks

A sheep’s thick winter fleece is incredibly deceptive. It can easily hide a thin, struggling animal until the problem becomes severe. That’s why you can’t manage your flock with your eyes alone; you have to use your hands.

A Body Condition Score (BCS) is a simple, hands-on method for assessing a sheep’s fat reserves. To do it, reach over the sheep’s back just behind the last rib and use your fingertips to feel for the spinal column and the short ribs (lumbar vertebrae).

• Too Thin (BCS 1-2): The bones feel sharp and prominent with very little tissue covering them.
• Ideal (BCS 3-3.5): You can feel the individual bones with some pressure, but they are well-covered and feel smooth.
• Too Fat (BCS 4-5): It’s difficult or impossible to feel the bones through the thick layer of fat.

Make a habit of checking a few sheep every time you’re out with the flock. This regular monitoring allows you to catch a drop in condition early. If you find animals are getting thin, you can act immediately by separating them for extra feed, deworming, or investigating other health issues before they become critical.

Maintaining Deep, Dry Bedding to Prevent Hoof Rot

Winter confinement areas can quickly turn into a muddy, manure-laden mess. This constant exposure to moisture and bacteria is the primary cause of painful hoof issues like foot rot and scald. A clean, dry place to stand and lie down is essential for hoof health and overall comfort.

The deep litter method is a simple and effective strategy. Instead of mucking out the shelter every few days, you add a fresh, thick layer of dry bedding (straw, wood shavings, or spoiled hay) right on top of the old pack. This keeps the surface layer clean and dry for the sheep.

This method has a powerful secondary benefit. As the layers underneath begin to compost, the microbial activity generates a surprising amount of heat. This creates a warm, insulated pad for the sheep to lie on, helping them conserve body heat. A well-managed bedding pack is both a mattress and a heater. Just be sure the shelter has enough ventilation to allow moisture from the pack to escape.

Using a Sacrifice Paddock to Protect Pastures

Letting your flock roam across all your pastures in the wet, dormant winter months can be devastating to your grazing land. The combination of heavy hooves on soft, saturated soil compacts the ground and destroys the roots of perennial grasses. Come spring, you’ll be left with a muddy, weed-prone field that will take a long time to recover.

The solution is to designate a "sacrifice paddock." This is a smaller, well-drained area where the flock is confined during the worst of the winter. It could be a small pasture, a corral, or any sturdy enclosure that gives them room to move around but protects your main fields. You will bring hay and water to them in this area.

As the name implies, this paddock will get torn up—that’s its purpose. But it is far easier and cheaper to reseed and restore one small, designated area in the spring than it is to rehabilitate all of your primary grazing land. Think of it as a strategic retreat to ensure you have healthy, productive pastures when the growing season returns.

Pre-Winter Parasite Control and Hoof Trimming

Sending your sheep into winter with a heavy parasite load or overgrown hooves is setting them up for failure. These are manageable issues that become a significant drain on their resources when their bodies are already stressed by the cold. Addressing them in the fall is one of the most effective proactive steps you can take.

A heavy internal parasite burden robs a sheep of vital nutrients, making it harder for them to maintain body condition. Before the first hard frost, it’s wise to conduct a fecal test to understand what, if any, parasite issues your flock is facing. A targeted deworming based on those results ensures they go into winter clean, able to put all their energy from that expensive hay toward staying warm and healthy.

Likewise, trim hooves before the ground becomes a cycle of freezing and thawing mud. Overgrown hooves can trap mud and manure, creating the perfect anaerobic environment for foot rot. It’s also much more difficult and unpleasant to handle sheep for trimming in the middle of a cold, wet winter. A good trim in late fall helps ensure they walk into spring on four healthy feet.

Winter doesn’t have to be a season of struggle and emergency. By focusing on these essential preparations—from shelter and water to nutrition and health—you shift from a reactive to a proactive mindset. This thoughtful planning is the key to a healthy flock and a less stressful winter for everyone involved.
