Why do hens cluck after laying eggs?

After laying an egg, the hen will cluck. This is a happy behavior and also a notification to the rooster. It is not an easy thing for a hen to lay an egg. It takes 10 to 20 minutes at the shortest and 4 to 5 hours at the longest. If you try to catch a hen that has just entered the nest, it will escape quickly. But when it reaches a certain time, even if you try to catch it, it will just stand up with its hair erected and would rather peck your hand with its mouth than stand up. Because the egg has reached the cloaca (the entrance to the cavity) at this time, the hen is concentrating on laying it!

At the same time, since it takes a lot of energy for a hen to lay an egg, it will take a period of rest after laying an egg before it leaves the nest. At this time, its spirit is in an excited state, so it clucks non-stop, not only to show the pride of motherhood, but also to notify the partner to let the rooster mate when the hen is "singing".
