Under natural conditions, a female chicken will lay her eggs and then sit on them to keep them warm so they can hatch into little chickens, I think it's called "going broody" or something like that. But many chickens used for egg production have had that instinct kind of bred out of them, to cause them to keep laying eggs instead of following the natural instinct to incubate and keep them warm so they can hatch.
