How do you keep your chickens healthy in winter?
, 10 min reading time
The winter months bring unique challenges for chicken keepers. Chickens are naturally resilient in cold weather, but they need extra care to stay healthy and comfortable through the colder months. A draught-free and well-insulated chicken coop, adapted feeding and good hygiene together form the foundation of responsible winter care. Getting this right prevents frostbite, reduced immunity and illness. In this article, we walk you through everything you need to know to keep your chickens safe, active and healthy during winter — from coop preparation to feeding, hygiene and protection against predators.
Why is winter care for chickens important?
Although chickens cope well with cold, they are vulnerable to specific winter problems. Frostbite on combs and wattles, respiratory issues caused by poor ventilation and a weakened immune system due to nutritional deficiencies are the most common risks. With the right preparation and daily attention, these problems are largely preventable.
- Prevent frostbite on combs and wattles by applying petroleum jelly during hard frosts.
- Keep the respiratory system healthy with adequate ventilation in the chicken coop.
- Adjust the diet to support the higher energy demands of winter.
- Make sure drinking water does not freeze.
Advantages and disadvantages of keeping chickens outside in winter
Advantages
- Natural behaviour: Chickens that can roam outside stay more active and experience less stress, even in winter.
- Better immunity: Exposure to fresh air and movement strengthens the immune system.
- Fewer coop problems: Active chickens peck at each other less and display fewer behavioural issues.
Disadvantages
- More maintenance: Winter care requires daily extra attention — from checking drinking water to replacing bedding.
- Predator risk: Shorter days mean chickens need to go in earlier and the coop must be securely closed.
- Frostbite risk: Chickens with large combs and wattles are more susceptible to frost damage.
Step by step: preparing your chicken coop for winter
- Check the coop for draughts: Seal gaps and cracks with rubber strips or sealant. Draughts are more harmful than cold.
- Install ventilation high in the coop: High ventilation prevents moisture build-up and mould without creating draughts at chicken level.
- Insulate walls and roof: Use foam panels or insulation foil for extra warmth without compromising the structure.
- Lay down a thick bedding layer: Straw or wood shavings on the floor provide warmth, absorb moisture and are easy to replace.
- Ensure frost-free drinking water: Use a heated drinker or replace water several times a day during freezing conditions.
- Check perches and nesting bars: Make sure there is enough space for chickens to sit close together and share body heat.
- Check the wire mesh and locks: Reinforce weak spots and make sure the coop is securely closed every evening against predators.
Feeding: more calories and protein in winter
In winter, chickens use more energy to keep themselves warm. Their nutritional needs change considerably as a result. A well-adapted winter diet is one of the most effective ways to keep your chickens healthy.
Energy-rich feed
- Add maize or grains to their feed. These are digested slowly and generate warmth from within.
- Give extra grains in the evening so that digestion produces heat throughout the night.
- A warm treat such as cooked porridge oats is popular with chickens and supports their energy balance.
Vitamins and minerals
- Use a vitamin and mineral supplement in the drinking water to compensate for any deficiencies.
- Regularly provide green feed such as cabbage leaves, kale or spinach for extra vitamins.
- Ensure sufficient calcium — for example via oyster shell grit — for strong eggshells.
Hygiene in the chicken coop during winter
A clean and dry chicken coop is important all year round, but even more so in winter. Lower temperatures and reduced ventilation cause moisture and ammonia to build up more quickly, which can lead to respiratory problems and mould growth.
- Remove droppings and wet bedding daily.
- Clean feed and water containers at least once a week with a mild disinfectant.
- Replace bedding regularly and check for mould beneath the floor layer.
- Air the coop briefly each day during calm, dry conditions.
Keeping your chickens active in winter
Chickens that stay active are less prone to stress, boredom and pecking behaviour. Movement also stimulates circulation and strengthens immunity.
Covered outdoor run
- Place a roof or tarpaulin over the run so chickens can scratch outside without standing in snow or rain.
- Scatter feed on the ground to encourage foraging and keep chickens occupied.
Enrichment and entertainment
- Hang vegetables such as cabbage, broccoli or beetroot as both a toy and a snack.
- Place a dust bath with dry soil or sand in the coop — essential for feather condition and skin health.
- Rearrange the coop layout occasionally to stimulate curiosity.
Protecting your chickens from predators in winter
In winter, predators such as foxes become more active and venture closer to inhabited areas. The shorter days mean chickens roost earlier, requiring extra vigilance when closing the coop in the evening.
- Regularly inspect the coop for weak spots in the wire mesh, wood and locks.
- Reinforce vulnerable areas with sturdy galvanised wire mesh.
- Close the coop every evening as soon as the chickens are inside — ideally using an automatic coop door.
- Bury the wire mesh at least 30 cm into the ground to prevent predators from digging their way in.
Comparison table: summer care vs winter care
| Aspect | Summer | Winter |
|---|---|---|
| Feeding | Standard layer pellets | Extra grains and calories |
| Drinking water | Refresh daily | Multiple times a day or heated |
| Ventilation | Open fully | Ventilate high, avoid draughts |
| Bedding | Thin layer of straw | Thick layer of straw or wood shavings |
| Predator risk | Moderate | Increased — close earlier |
| Activity | Free range | Covered run or indoor foraging |
Frequently asked questions about chickens in winter
How cold is too cold for chickens outside?
Most breeds tolerate temperatures down to -10°C provided they have a draught-free and dry coop. Chickens with large combs are more susceptible to frost damage and need extra protection.
Do chickens need to stay inside all winter?
No, chickens do not need to stay indoors all winter. A covered outdoor run where they can scratch and forage in the dry is sufficient. Movement and fresh air are beneficial for their immune system.
How do I prevent frostbite on combs and wattles?
Apply petroleum jelly to the combs and wattles of your chickens during hard frosts. This creates a protective barrier that significantly reduces the risk of frost damage.
Do chickens lay fewer eggs in winter?
Yes, due to shorter days and less light, most chickens lay fewer or no eggs in winter. Artificial lighting in the coop can partially maintain egg production, but chickens should also be given the opportunity to rest naturally.
How do I stop drinking water from freezing?
Use a heated drinker or place the drinker on a heating plate. If you do not have a heated system, replace the water several times a day during hard frosts.
Are you well prepared for winter?
When is extra action needed?
- If your chicken coop is not insulated or has draughts
- If the drinker regularly freezes overnight
- If your chickens show signs of stress or illness such as lethargy, puffed-up feathers or nasal discharge
- If the wire mesh or locks on the coop are no longer in good condition
Common mistakes in winter
- Sealing the coop completely without ventilation — moisture and ammonia are more harmful than cold
- Forgetting to check drinking water for ice
- Not providing enough calorie-rich feed while energy demands increase
- Closing the coop too late in the evening and giving predators an opportunity
