That seems to be a lot of effort, wouldn't it be easier to do what we do in the West and debeak the chickens, feed them stuff to make them grow (that have the side effect of making us infertile and resistant to anti-biotics) and cram the chickens into tiny cages to live out their miserable lives before we slaughter them and eat them, or dispose of them when they have laid all the eggs they can (about 6 weeks I believe is the life span of meat birds, which grow so massively pumped by hormones that they can no longer stand).

Maybe with the fear of bird flu in China these crazy eggs may be preferred by the buyers. Maybe the chickens are hoping so too!
