Please say in your own words, what is the reason for the loss of chicks?

Hens with chicks pecked at the remaining rice grains, insects and ants in the yard, very complacent. The eagle flew over it, and the hen thought it was going to catch the chicken and spread its wings to protect it. The eagle had no choice but to leave, and the hen let go of the chicken and continued to eat as usual. After a while, a crow flew down and stopped beside it. The hen sheltered the chicken. The crow teased the chicken, and the hen thought there was no threat, so she let the chicken drink water and peck at it without shelter. The crow waited until the hen was defenseless and flew away with a chick in her mouth.

It shows that turning a blind eye to some potential problems will have serious consequences. Dangers visible in the light are relatively easy to prevent, and hidden dangers are more deadly.
