Chicken which roam in the wild

I am 60. Last time, many homes reared chicken and the kitchen waste was used to feed them.

Most of the times, kitchen wastes was not enough and extra feeds used continued to cost more.

Following that kind of situation, chicken farms was developed and today every chicken grows up within high technology structures. These chicken grows faster than the roaming chicken in the wild.

Roaming chicken has been outnumbered by high-tech chicken.
