This mother duck was lucky: she lost all her children, but they managed to save them.
Someone was filming mom duck walking around with several of her ducklings, when one of them slid down a sewer they were passing through.
Realizing that she had lost one of her children, she began to circle around the sewer. Until finally all her young end up falling.
By how it reacts there is no doubt that the bird does not know what to do, besides continuing to circle around.
When watching the video, users left many comments, concerned about the fate of the ducklings and the mother. Fortunately, the second part of the video has been posted and it shows how a person enters in the drain and saves the little ones.
