Eggs are a typical foraging food. Our ancestors likely grabbed any eggs they could find when they could find them. Eventually we started farming in SE Asia and the ancestors of the chicken hung out near the plentiful feedstock of rice fields and made their nests nearby. Over time they got used to humans and we kept taking their eggs, as we had done when we found their eggs in the wild. Around 3,000 years ago we had the chicken, an easy to care for food pooping source of meat that we had bred to poop food regardless of time of year. The bird later spread all over the planet.
Fastfoward to more recent times and we have selectively bred and drugged up a bird that reliably poops food every day and can yield the maximum amount of meat possible.
