Keeping Backyard Chickens Healthy in Summer: How to Prevent Heat Stress and Red Mite
10 July 2026
The warmer summer weather can bring a few seasonal challenges for backyard chicken keepers. The two biggest concerns during the summer are heat stress and red mite. Fortunately, with a few simple management steps, you can help keep your flock comfortable and healthy throughout the warmer months.
Recognising the Signs of Heat Stress
Unlike people, chickens cannot sweat to cool themselves down. Instead, they rely on panting and releasing heat from their bodies. While most birds cope well with temperatures up to around 28°C, prolonged periods of hot weather can quickly lead to heat stress, particularly if coops are poorly ventilated.
Common signs of heat stress include:
- Panting or open-beak breathing
- Holding their wings away from their body
- Lying flat on cool ground or bedding
- Seeking shade and becoming less active
- Drinking more water than usual
- Eating less
Spotting these signs early allows you to make changes before your birds become seriously affected.
Why Heat Stress Matters
Heat stress doesn't just make chickens uncomfortable. If birds become too hot for too long, it can have a significant impact on their health and wellbeing.
During hot weather, you may notice:
- A reduction in egg production
- Thinner or weaker eggshells
- Reduced appetite
- Increased water consumption
- Digestive upset or diarrhoea
- Greater vulnerability to respiratory problems
In severe cases, prolonged overheating can become life-threatening, making prevention far better than treatment.
Simple Ways to Keep Your Chickens Cool
Thankfully, helping your flock stay comfortable during summer doesn't need to be complicated.
Provide Plenty of Shade
Ensure your chickens always have somewhere to escape direct sunlight. Trees, shelters, tarpaulins or shaded runs all provide welcome relief during the hottest part of the day.
Improve Coop Ventilation
Good airflow is essential in warm weather. Well-ventilated housing helps reduce heat build-up while improving air quality.
Keep Water Fresh and Cool
Fresh, clean drinking water should always be available and checked regularly throughout the day during hot spells. As birds drink considerably more in warm weather, keeping drinkers topped up is essential.
Avoid Overcrowding
Giving chickens enough space allows them to spread out and helps prevent excessive heat building up inside the coop or run.
Summer Also Means Red Mite Season
Warm weather creates ideal conditions for red mites.
Red mites are one of the most common parasites affecting backyard chickens in the UK. Unlike lice, they don't live permanently on your birds. Instead, they hide in cracks, perch ends and nest boxes during the day before emerging at night to feed on your chickens' blood.
Because their life cycle can be as short as 7-10 days, populations can increase rapidly during the summer if left unchecked.
How to Spot Red Mite
Early infestations can be difficult to detect, so regular inspections are important.
Pay particular attention to:
- Perch ends
- Nest boxes
- Cracks and crevices within the coop
Regular monitoring allows you to identify problems before infestations become severe.
The Chicken Vet Mite Traps and Sticky Pads provide a simple and effective way to check whether mites are present in your chicken coop, while also helping to monitor and trap persistent parasites.
Prevention is Easier Than Treatment
Good coop hygiene plays an important role in reducing parasite pressure throughout the summer.
A torough cleaning routine should include:
