Can a chick hatch naturally by itself with only chicken?

No, a chick cannot hatch naturally by itself with only chicken. Here's why:

* Fertilization: For a chick to develop, the egg needs to be fertilized by a rooster. This means the sperm from a rooster must penetrate the egg.

* Incubation: After fertilization, the egg needs a consistent warm temperature for approximately 21 days to allow the embryo inside to develop fully. This is typically achieved by a broody hen sitting on the egg.

In summary: A chick requires both fertilization and incubation for development, which cannot happen without the involvement of a rooster and either a broody hen or an artificial incubator.
