There seems to be a misconception that chicken farms are like the good old days on the family farm where McDonald would raise chickens, collecting their eggs every morning, then slaughtering them for Sunday lunch when they got too old. Today's industrial farms are much more specialized, with chickens producing eggs or meat, but not both. And this isn't even new. My Dad, 85 years old, still talks about going out before breakfast to feed the coal fired furnaces my Grandpa used to keep his chickens warm in the winter until the trucks came to take them for processing, and they didn't sell eggs.
