Taking the temperature of a chicken is important for a variety of reasons. For cooked chicken, the internal temperature must reach 165 °F (74 °C) to ensure food safety and avoid foodborne illnesses such as salmonella. The core body temperature of a live chicken, on the other hand, typically ranges between 105 and 107 °F, averaging 106 °F. This temperature can vary depending on factors such as ambient temperature, age, breed, and health. Young chicks are especially vulnerable to temperature changes and can quickly die if they get too cold. Therefore, it is crucial to monitor their body temperature to ensure their well-being.

What You'll Learn
The core temperature of a chicken is between 105 and 107°F
The core temperature of a chicken is usually between 105 and 107°F (40.5–41.7°C), with an average of 106°F (41.1°C). This temperature range is higher than that of the average human being, which is 98.6°F (37°C). A chicken's body temperature varies according to several factors, including the ambient temperature, age, breed, gender, activity level, and state of health. For instance, the body temperature of a chick is about 103.5°F (39.7°C) when it hatches, and it relies on external warmth to survive.
Taking the temperature of a chicken can be done with a digital thermometer, such as the Omron 246, inserted about an inch into the chicken's vent until the thermometer beeps, indicating a constant reading. Alternatively, an infrared ear thermometer, such as the Braun Thermoscan5 IRT6500, can be placed against the chicken's featherless facial skin, avoiding the comb or wattles. It is important to note that handling the chicken may cause slight temperature elevation due to stress.

Use a digital thermometer inserted into the chicken's vent
To take the temperature of a live chicken, you can use a digital thermometer inserted into the chicken's vent. This method is more invasive than using an infrared ear thermometer but may provide a more accurate reading.
To do this, insert the thermometer about one inch into the chicken's vent. Hold it in place until the thermometer beeps, indicating that it has reached a constant reading. This reading will give you the chicken's core temperature.
It is important to note that a chicken's temperature can vary depending on various internal and external factors. Therefore, taking the chicken's temperature may not be very helpful in diagnosing illness unless you know the bird's normal temperature range.
Additionally, the chicken's skin temperature will be lower than its core temperature. So, if you are using an infrared thermometer on the chicken's skin, you should be aware that the reading will differ from the core temperature.

Alternatively, use an infrared ear thermometer
The thermometer works by remotely detecting the eardrum temperature. The eardrum is a very reliable indicator of body temperature because it is less affected by external temperature changes. It is also close to the hypothalamus, which regulates body temperature.
To get an accurate reading, the key is to ensure that the infrared sensor points directly at the eardrum and that there is nothing in between. Any blockage in the ear canal, such as earwax, fluid, or dirt, will interfere with the radiation reaching the sensor and result in a lower reading. Therefore, before taking the chicken's temperature, gently pull back the ear to straighten the ear canal and ensure the probe is aimed at the eardrum.
Infrared thermometers are also useful for checking the surface temperatures of griddles, pans, and ovens, as well as refrigerated or frozen items. However, they cannot be used to determine the internal temperature of solid foods like chicken.

The ideal internal temperature for cooked chicken is 165°F
While there are various methods for checking the doneness of chicken, such as checking if it's firm when pressed or no longer pink inside, the most accurate way is to use a food thermometer to measure its internal temperature. This is especially important to avoid foodborne illnesses like salmonella, which is a very hardy bacteria that can be safely eliminated at temperatures of 165°F (74°C).
It's worth noting that the doneness of chicken can also depend on the cut of meat. For example, the breast meat will become dry if taken too far above 150°F (65.5°C), while the leg meat needs to reach a temperature of 160-170°F (71-77°C) for the connective tissue to dissolve into gelatin. In addition, the size of the chicken matters; a large piece of chicken, like a whole bird, will have more thermal mass, affecting how heat is distributed.
When taking the temperature of a live chicken, it's important to remember that handling the bird can slightly elevate its temperature due to stress. Young chicks, in particular, can struggle to regulate their body temperature and rely on external warmth, so it is crucial to ensure they don't get too cold.
In summary, to ensure the chicken is cooked properly and safe to eat, it is recommended to use a food thermometer and aim for an internal temperature of 165°F (74°C). However, it's important to be mindful of the variations in doneness depending on the cut and size of the chicken.

Chicken can be cooked at lower temperatures if held longer
Chicken is typically cooked at 165°F (74°C) to ensure that all bacteria are destroyed and the meat is safe to eat. However, it is possible to cook chicken at lower temperatures if it is held at that temperature for a longer period. For example, chicken can be cooked at 157°F (69.4°C) for 31 seconds or at 145°F (63°C) as long as it is held at that temperature for an appropriate amount of time.
Cooking chicken at lower temperatures for longer periods can result in juicier and tastier meat. The lower temperature allows the chicken to retain more moisture, and the meat will not be dry. Additionally, the appearance of the chicken may vary depending on the cooking temperature and time. For example, chicken cooked at a low temperature for a long time will have a different colour than the same chicken fried quickly on high heat.
It is important to note that the doneness temperature for chicken may vary depending on the cut of meat. For example, breast meat is leaner than thigh meat, and the leg meat needs to reach a higher temperature range of 160-170°F (71-77°C) for the connective tissue to dissolve.
When cooking chicken at lower temperatures, it is crucial to ensure food safety. Salmonella bacteria, which can cause foodborne illnesses, can be safely eliminated at temperatures lower than 165°F (74°C). By using pasteurization tables and tracking the chicken's carry-over cooking, it is possible to cook chicken at lower temperatures while still ensuring food safety.
In summary, chicken can be cooked at lower temperatures if held for a longer period, resulting in juicier and tastier meat. However, it is important to ensure food safety by using the appropriate tools and techniques to monitor the temperature and cooking time.

Frequently asked questions
The core, or deep body, temperature of a fully feathered chicken normally ranges between 105 and 107 degrees, averaging 106 degrees under normal circumstances. The normal temperature of a chicken will depend on the ambient temperature as well as factors such as the chicken’s age, breed, gender, activity level and state of health.
You can use a digital thermometer inserted about an inch into the chicken’s vent until the thermometer beeps and indicates a constant reading. Alternatively, you can use an infrared ear thermometer placed against the chicken’s featherless facial skin but not on the comb or wattles.
The internal temperature of a chicken should be 165°F (74°C) to ensure it is safe to eat. This temperature is reached by pushing the tip of a thermometer probe through the thickest part of the meat and pulling it slowly up through the meat.
