The ancestors of dogs, including foxes and coyotes are a species of mammals living almost like weasels in the cavity is about 400 million years ago. And dogs as we see today is evolved from a small dog, gray. In the late Ice Age, about 40,000 years ago, wolves and people live together in groups of prey in packs. The wolf and prey often compete, even kill each other. But would the wolf began to scavenge the scraps left by humans.

Chickens are gregarious birds. They can approach community for incubation and chick rearing. The chicken in the flock individuals vied dominant, established the so-called “social hierarchy” in which individuals have the advantage of access to food and nesting sites. The rooster or hen lost from the herd will break this order for a short time until a newly established hierarchy. The addition of hens – especially young chickens – and above available can lead to fights and injuries. When the rooster find the bait, it will cluck, picking up food and drop down, call the other chickens to eat before. Similarly, can observe this behavior when they call mother hen chicks to eat.
