Studies using monitors, tape recorders and video cameras have shown that the eggs do indeed communicate with the hen during hatching. When the hen hears the chick cooing in her egg, she answers with a cooing. The hen and the chicks responded, and a few hours later, the chicks broke out of their shells.
We all know that fetal education occurs during pregnancy, but could a hen communicate with her eggs during hatching? What should we say if we communicate? What does this communication do?
To answer these questions, scientists have studied the incubation process of eggs. They studied hen – egg communication by placing sensitive microphones in the hen’s nest.
