Imminent egg hatching in Uccle Saint Job!
Since noon yesterday, eggs are chirping in Uccle! The hatching process takes long hours. The first step for the chick is to pierce an internal membrane in the egg so there is more room to turn around and methodically shear the shell on the side of the blunt end.
As soon as this membrane is pierced, the chick breathes with its lungs and at the same time begins to chirp. It is certainly the first signal he gives to his parents. Communication has therefore already begun between chicks and parents.
Listen, it's very exciting.
The attached video allows you to hear some of these chirps.
Hatching will be (very) soon!
