In my old school I was in agriculture, and we had tonnes of chickens, because people kept throwing them over the fence. We also raised chickens specifically for being eaten, but they were extremely well looked after, got to run around the ag farm and everything, but when they were old enough, they would dissappear and the school would sell the chicken meat to help fund the ag farm. We also raised cows, and would take them to shows in which the first day was judging on appearance and everything, afterwards everyone would go home and leave the cows behind because the second round judged their meat, so the cows were slaughtered. The meat from that was also sold to help fund the ag farm.
I felt I had to say that for some odd reason....
