Today I read that chickens start to lay eggs at 4 months of age. That didn't surprise me. What surprised me was that they stop at 12 months of age but can live 5 to 11 years old. Is this true or does the egg laying just slow down? To what age do they lay eggs and then what do I do with them after they're done? Do they just become like grandmothers to the new born chicks? My other question is at what age would you absolutely not slaughter a chicken to put on the table for dinner?Does the meat get so tough that you can't even slow cook it to tenderize it? What about extra roosters? I don't know what I have yet but I'm guessing there are a couple of roosters in there ... I hope so anyway. How many roosters should I have per chicken and then what do I do with the extras.
