At a level of 60 dB sound pressure level (re 20 μN/m2), their hearing range extends from 9.1 Hz to 7.2 kHz, with a best sensitivity of 2.6 dB at 2 kHz. Chickens have better sen- sitivity than humans for frequencies below 64 Hz; indeed, their sensitivity to infrasound exceeds that of the homing pigeon.
Do loud noises bother chickens?
In addition, studies have shown that loud noises such as found near airports, rail road tracks or loud hydraulic or pneumatic equipment and machinery close to the chickens leads to lower egg production, stunted growth, higher blood pressure, stress and fatigue in the chickens.
Do chickens have a good sense of hearing?
Most birds, including chickens, hear well. Birds have ears on both sides of their heads, and unlike humans, birds do not have external flaps on their ears. Instead, the opening of the ear is covered by a special tuft of feathers. These feathers protect the ear without impairing perception of sound.
Are chickens scared of noise?
Studies show that just as in humans, major abrupt changes to the day and night cycle of the chickens, such as waking up the chickens at night with loud noises, will lead to stressed and anxious chickens.
Why do chickens rely on hearing?
Chicken hearing is important since they are low on the food chain, so any advance notice of a predator’s presence is critical. In addition to their ears, chickens also have sensory nerves in their feet, so they are able to feel vibrations in the ground, which is extremely useful to “hear” predators approaching.
How far can a chicken hear?
At a level of 60 dB sound pressure level (re 20 μN/m(2)), their hearing range extends from 9.1 Hz to 7.2 kHz, with a best sensitivity of 2.6 dB at 2 kHz. Chickens have better sensitivity than humans for frequencies below 64 Hz; indeed, their sensitivity to infrasound exceeds that of the homing pigeon.
Can chickens deaf?
There’s no such thing as a deaf chicken, and that discovery was accidental. Scientists studying how drugs can cause hearing damage were administering a drug known to cause hearing loss to chickens as part of an experiment to help human hearing loss.
Do chickens have empathy?
Empathy is one of the most interesting things about chickens. If a peer is hurt, stressed, or even happy, other chickens will not only understand, but share those feelings.
What emotions can chickens feel?

If you are approaching your chickens to get closer to them, you’ll have to use gentle voices and noises to keep from scaring them. Thunder, loud automobiles, motorcycles, lawn equipment, or even distant gunshots can frighten your chickens.
What Colours do chickens not like?
Breeding practice shows that red, green, blue, yellow and other light colors have certain adverse effects on the physiological function and growth of chickens. However, in the breeding process of chickens, this problem has long been ignored by people, causing undue losses to chicken farms (households).
Why do chickens scream when they lay eggs?
The noise is not a cluck but a cackle. Cackling is a “buck-buck-buck-badaaack” sound, repeated often over as long as 15 minutes after laying an egg and thought to draw predators away from the nesting area. It may also be used to aid mating and as a location finder for the flock.

Can birds get hearing loss?
Trauma to the inner ear in birds, due to acoustic overstimulation or ototoxic aminoglycosides, can lead to hair cell loss which is followed by regeneration of new hair cells. These processes are paralleled by hearing loss followed by significant functional recovery.
