The ears of chickens are located behind the eyes, above the cervical vertebrae, and are covered with flaky feathers. This is the ear canal of the chicken.
A chicken’s hearing is basically done by its ears, and its skin or feet have a very weak ability to sense sound waves. Without ears, it can’t hear anything.
The ears of chickens are the sound organs of chickens. In addition, they can maintain the balance of the chicken’s body and reduce the pressure of Lunet. Birds have small heads, and of course their ears are small, unlike mammals, which have external ears, except for owls.

3. Egg production, an average hen lays about 300 eggs per year, and the average hatching rate is more than 70%.
4. Others, the ratio of material to meat is generally 1.50~2.00:1; the ratio of material to egg is generally 2.0-2.5:1.0.
5. The longest survival of chickens is generally 13 years (rearing environment).
6. Laying hens: generally start production in about 110 days (factory breeding), and they will be eliminated at 72 weeks, and the weight will be about 2 kg when eliminated.
