I think the new practice should be economically advantageous to those with large economic scale. Such a law should hurt smaller operations and further centralize food production. I'm going with the protect the crony theory for why they would vote "yea" on such a bill.
With new technology machines to do this will no doubt be expensive. The amount of benefit is proportional to the number of chicks you have to grow into chickens to produce eggs and meat. Whereas the price of such a machine is constant and should probably be just one for all of the eggs. This is my reasoning that this should cause centralization.
