What about the pet food industry? Don't a lot those males and layers, after their prime laying yrs, go into the pet food industry? The pet food market is a multi billion dollar business annually. It's hard to imagine that commercial chickens producers don't find a profitable way to make use of all those birds that are either not laying or not large enough for the meat market.
I do feel that our food production, whether for people or pets, is somewhat of a paradox. On one hand we are told that there is an abundance of food produced that is wasted annually. And, on the other hand, we are told we have to use potentially harmful farming methods because we have to feed the world. And, yet there are still masses of starving people throughout the world, including right here in the USA. Go figure.
