Why Does a Chicken Lay an Egg Almost Every Day When Other Birds Don't?

A wild red junglefowl hen lays only about a dozen eggs a year, while a modern hen can approach 300. So why does a chicken lay an egg almost every day when other birds don't? The answer runs through five reasons: a bird that was already built to lay, thousands of years of selective breeding, a body that listens to daylight, an egg-making assembly line inside the hen, and a skeleton that doubles as a calcium store. The last reason is not about chickens at all, it is about you. You will see where chickens came from, what the 2022 archaeology study found in Thailand, how light controls egg laying, how a shell is built in about 20 hours, and why a hen does not need a rooster to lay. Where a number is an estimate, the video says so. If you like everyday questions explained simply, subscribe to Darnlo for more. #ChickenEggs #AnimalFacts #Darnlo
