Why Do Chickens Make Noise Early in the Morning After Laying an Egg?

Have you ever wondered why a chicken makes a lot of noise early in the morning, especially after laying an egg? This article explores several theories and insights into the fascinating world of chicken behavior.

Understanding the Chicken's Internal Clock

Roosters do not just crow because of an alarm clock; they have an internal clock that helps them anticipate sunrise. Like all birds, roosters sing or crow in a daily cycle, but the primary function of their sunrise song is to establish their territory. However, it is not limited to just the roosters; hens also produce certain vocalizations, although these are often less pronounced.

The chicken's egg song is a unique vocalization that marks the moment of laying an egg. This behavior is particularly prominent in hens, and it’s often associated with the rooster's crowing. A hen will often vocalize shortly after laying an egg, which can be heard as a series of low, clucking sounds followed by the characteristic “puck-AUH!”

The Evolutionary Purpose of Egg Laying Vocalizations

There are several theories regarding why hens vocalize after laying an egg. One theory suggests that it may serve to attract other chickens to lay eggs in the same spot, creating a larger clutch that can be incubated by a broody hen. This behavior can be seen as a means of improving the survival chances of the entire flock by creating a communal effort to protect the new eggs.

Additionally, the vocalization could serve as a signal to potential predators, alerting them to the presence of a vulnerable egg and drawing their attention away from the hen that just laid the egg. The instinct to communicate could have evolved as a way to protect the vulnerable egg and the flock as a whole. This is especially critical for hens in a flock, as they are more vulnerable when alone, and a large flock offers better protection.

Chicken Behavior in Response to Human Presence

Interestingly, chickens often make a great deal of noise when they spot a human approaching. This behavior can be attributed to their natural inclination to alert the flock to potential threats. However, it is not exclusive to hens; roosters, ducks, and guineas also make loud noises in response to human presence, with ducks and guineas being particularly vocal.

For instance, my chickens, ducks, and guineas create a massive racket when I approach, with the ducks and guineas being the loudest. They will come running, hopping, and flying from all corners of the four-acre area into one large group, resembling a herd of feathered buffalo. This behavior is not only entertaining to watch but also a testament to the natural alertness of these birds.

Conclusion

Chickens make a lot of noise early in the morning after laying an egg due to a combination of their internal clocks, communication with the flock, and a natural alertness to potential threats. While it may seem disruptive to us, it is a crucial part of their behavior and survival strategy. Understanding and appreciating this behavior offers valuable insights into the fascinating world of avian life.
