Winter Animal Care

How cold is too cold for farm animals?

There is no single answer, because tolerance depends on species, breed, coat, age, condition and shelter. Wind and wet conditions make cold much harder on animals than dry, still cold. Many animals handle cold well if they stay dry, out of wind and well fed.

Ask your veterinarian or extension office what is normal for each of your species and what temperatures call for extra help, especially for young, old or thin animals.

Wet is worse than cold. An animal soaked by freezing rain or sleet loses heat fast, so give every animal a dry place to retreat and check that they actually use it.

• Wind and wet raise cold stress more than low temperature alone
• Young, old and thin animals need extra attention

What kind of shelter do animals need?

Provide a dry, draft-free area with good bedding and a wind break. Ventilation still matters. Closing a building completely traps moisture and ammonia, which harm animals more than cold air does.

Clean and refresh bedding regularly, and avoid damp patches. Give each animal enough room, as crowding raises moisture and spreads disease.

Keep an eye on heating devices. Heat lamps and heaters are a leading cause of barn fires, so ask your extension office or fire department about safe options.

• Keep bedding dry and clean
• Block drafts but keep ventilation
• Avoid crowding
• Use only safe, properly installed heat sources

How do I keep water from freezing?

Animals need liquid water daily. Use insulated or animal-safe heated waterers, and check them several times on freezing days. Cold water discourages drinking, and dehydration develops quietly.

Have a backup plan for power loss, including spare buckets and a way to haul water. Keep electrical equipment safe from moisture and chewing.

Never break ice with force near an animal, and avoid letting animals stand on thin ice over ponds. Use a safe tool from outside the water and keep children away from frozen ponds.

• Check water at least morning and evening
• Keep cords and heaters out of reach of animals
• Keep a plan for hauling water by hand

How should feeding change in winter?

Animals burn more energy keeping warm, and good quality forage is the foundation. Ask your veterinarian or extension office how to adjust rations for your species, condition and weather.

Make changes gradually and watch body condition by hand, not by eye alone, since thick winter coats hide weight loss. Keep feed dry and protected from pests and moisture.

Weigh or measure animals at the start of winter if you can, so changes show up as numbers instead of guesses. Your vet can teach you condition scoring for your species.

• Provide quality forage as the base
• Check body condition by feel
• Change feed gradually
• Keep feed dry and secure

What winter warning signs should I watch for?

Watch for shivering, lethargy, reduced eating or drinking, limping, frostbite on combs, ears or feet, and any change in behavior. Do your checks daily and note anything unusual.

Call your veterinarian promptly if you see worrying signs. Do not treat animals with products without veterinary advice, and do not attempt home procedures.

Frostbite can follow cold nights in birds with large combs and in animals with exposed ears or feet. If you see pale, dark or swollen tissue, call your vet.

How do I handle special groups such as poultry, young animals and older animals?

Poultry need dry, ventilated coops with roosts, and extension offices such as UNH and the University of Minnesota publish winter flock guidance. Young and old animals tend to have less cold tolerance and often need extra care and closer observation.

Keep wild birds away from poultry feed and water, since disease reporting and biosecurity rules vary by state. Ask your state veterinarian or extension office what applies.

Special care applies to animals that are sick, pregnant, newly weaned or recently moved, because stress and cold combine badly. Ask your vet for an individual plan.

• Check poultry combs, wattles and feet
• Give young animals dry, draft-free resting space
• Ask your vet about animals that are old, pregnant or ill

How do I plan for storms and power outages?

Keep emergency supplies for animals, including extra feed, water, bedding and flashlights. Write down contact numbers, including your vet and a backup caretaker.

Ready.gov and your county emergency management office offer planning materials. Walk through what you would do if roads closed for several days.

Keep a log of cold snaps and how your animals handled them. After a winter or two you will know where your housing needs work.
