Why Temperature Matters

Temperature control is essential to keeping your chickens healthy and alive in extreme cold or hot temperatures.
The temperature range that chickens can tolerate varies depending on the age and breed of the chicken. For example, day-old chicks can withstand temperatures as high as 95 degrees Fahrenheit, while adult chickens should be kept at temperatures below 80 – 85 degrees Fahrenheit. However, some general guidelines apply to all chickens such as 36 hours old or younger chicks shouldn’t be exposed to temperatures above 105 degrees Fahrenheit. Adult chickens should be kept out of direct sunlight to prevent them from heating. All chickens are susceptible to heat stress when the temperature exceeds 90 degrees Fahrenheit. At this point, they may stop eating and drinking, and their egg production may suffer. As a result, paying attention to the temperature inside your chicken coop, especially during the summer months, is important. Read More: How to Keep Chickens Warm in Winter Without Electricity.

The Ideal Temperature Range for Chickens

Watching out for signs of heat exhaustion can help you catch the problem early on so you can cool them off before it becomes fatal.
The ideal temperature range for chickens is between 65 and 75 degrees Fahrenheit. Chickens are most comfortable in this temperature range and will lay the most eggs within this temperature range, as well. Although chickens can tolerate extreme temperatures, some temperature ranges are too hot or too cold for them. Temperatures below 32 degrees Fahrenheit can cause frostbite, while temperatures above 95 degrees Fahrenheit can be fatal. Here is a table to show the appropriate max temperatures for chickens based on their age:
Chicken AgeTemperature
Newly Hatched Chicks95 Degrees F
One Week Old Chicks90 Degrees F
Two Week Old Chicks 85 Degrees F
6 Week Old ChicksBetween 45 Degrees F and 80 Degrees F
Adult ChickensIdeal Temp is 70-75 Degrees F, At Least 45 Degrees F
By providing a warm, draft-free coop, you can help your chickens to stay healthy and comfortable all year round.

Signs of Heat Stress in Chickens

Chickens are remarkably resilient creatures, but even they can succumb to the heat if the conditions are extreme enough. There are a few signs to watch out for that can indicate that the chicken is experiencing heat stress.

Lethargy and Weakness

If a chicken is too hot, it will start to feel weak and listless. Your chicken may stop moving around and stop eating. You may also see that your chickens are sleeping a lot.

Increased Heart Rate

A chicken’s heart rate will increase when it is too hot. Increased heart rate can cause heart attack and other heart conditions that can be fatal.

Difficulty Breathing

Hot temperatures can make it hard for chickens to breathe. They may open their beaks and gasp for air. If you see any of these signs in your chickens, it’s important to take action to cool them down. Move them into a cooler area, provide fresh water, and mist them with cool water if possible. Read More: What is the Best Bedding for Chickens in the Winter?

  • Move the chicken to a shaded or cooler area.
  • Spray the chicken with cool water.
  • Place a fan near the chicken to create a breeze.

How to Prevent Heat Stress in Chickens

Here are some tips to prevent heat exhaustion:
  • Provide access to shade and water at all times. Chickens need to be able to escape the heat and will drink more water than usual to stay hydrated.
  • Monitor the temperature. While chickens can handle warm weather, if the temperature gets too hot (over 90 degrees Fahrenheit), they can start to experience heat stress.
  • Keep an eye on their combs and wattles. These fleshy growths on a chicken’s head help regulate its body temperature. If they become bright red or swollen, it’s a sign that the chicken is overheated.
  • Inspect for pests. Fleas, mites, and ticks love the warm weather just as much as your chickens, so check them regularly and treat them accordingly if any problems arise.

Conclusion

Depending on the breed of chicken, the climate where they live, and other factors, different temperatures could be too hot or not hot enough. We hope this article has given you a good starting point regarding what temperature ranges are safe for your backyard chickens. Always be sure to do your research and follow the guidelines set by your specific state or country when it comes to raising poultry!
