I have serious doubts about this. Federal regs are always the bare minimum required for survival. Currently, in California, we have a proposition on the ballot to require farmers to provide a minimum of one square foot of cage space per bird. This is supposed to be an improvement on current federal regulations. I don't think anyone on this site thinks that is a good quality of life. The box I carried my chickens home from purchase in was bigger than that. Lots of us raise our own chickens because the factory farms are unacceptable conditions to us.I can guarantee you that their egg and bird conditions are as good or better than anything you can provide.
The numbers you post are helpful to put things into perspective, however.
