I am a student that was asked to design a chicken coop and to explain all of the expenses. I am wondering what do you do with the chickens after they stop laying eggs like they used to? Do you sale them or just let them grow old? I have been looking different places and it seems that laying chickens do not make for good meat birds. I have some classmates that assume that you would sale the chickens for meat. Is that true? Thank you for your time.
