A creepy cartoon about a chick cuckoo

Perhaps everyone knows that cuckoos are the main scoundrels of the bird world, which are discouraging with their impudence. And the main and most famous fact of their biography is that they lay their eggs in other people's nests. And, it would seem, everything is not so bad, except for the complete lack of parental instinct. What’s also creepy is that cuckoo chicks, after hatching, kill the young of their nest owners to get more food. Let's watch a cartoon dedicated to this wild law of nature.
