Interesting facts about chickens

Posted on Mar 11, 2022      121

Among all other animals and birds raised on an industrial scale, chickens occupy a special place. They are bred both for eggs and meat, and in some countries they are an integral part of traditional cooking. They spread around the world in times immemorial, and since then you can find chickens in every corner of the Earth, even on many remote islands. Being rather unpretentious birds, they feel well in captivity and reproduce quickly.

Facts about chickens

  • Chickens can remember “by sight” all the relatives in their coop.
  • People think chickens communicate with each other with simple clicks and clucking, but in fact, it is a language of communication. Researchers have described over thirty different meanings of avian “conversation.”
  • These domestic birds can experience emotions, as well as expressing feelings of compassion and mercy.
  • The ancestors of modern chickens originated in Asia, where they were domesticated.
  • The hen does not need a special nest for laying eggs - it can do it almost anywhere.

  • Chickens “start” the egg-laying process only in light, no matter whether artificial or natural.
