1) Most of you on here would be put out of chickens. Your 4'/chicken is a "cage". 2) 250 million commercial layers in USA, where would they go? How would you like to be the bottom 100 hens in a 10,000 cageless building? A building is just a "huge" cage. 3) Free range only, ok, how big of a pen would it take to give them comfort/safety. How long in the pen before it needs to be moved so the birds aren't tramping in their own excrement? Is a pen any better than a building if the room/hen isn't any better? 4) No pens, true free range, good luck gathering eggs, controlling diseases, predators, etc. I'd hate to think of the cost of eggs in this system. It's great to say it's cruel & stop the "cage" industry but what would you replace it with?
