Arguments for intensive poultry farming?

Most poultry farms raise chickens for eggs they house them feed them and clean their coops daily. The poop and urine are washed out every day collected and put into trucks that sprays that into orchards which reduces the use of Commercial fertilizers. One thing that many do not know is these laying hens are not normally sold as food for humans, as they get three years of age or more they are to tough to eat, so they do process them into other foods for cats and dogs. With a poultry Business They have a House that does nothing but incubate eggs once the chicks hatch they are then sold back to the local farms to replace older hens. This limits how far you have to take the eggs and chickens to market lowering emissions for food. Since I do not believe in global warming that is man made, (I believe Sun makes the earth warm from solar flares) it would reduce the amount of fuel it costs to deliver a truck load of eggs. On the west coast California banned having farms out in the country with 100,000 chickens because it polluted the environment so they shut down the egg company's and many have to get their eggs from Colorado, figure out how much fuel that uses from Colorado to california every day. hope this gives you a ideal.
