Why Won't McDonald's Accept a Requirement for Even Just 5% Cage-Free Eggs?

Meanwhile, McDonald's Europe is Going 100% Cage-Free

The battery cage photo above is described this way: "95% of egg laying hens in the United States spend their entire lives in a battery cage like this one. 6-8 birds are confined to a cage this size; each bird having less room than a standard sheet of notebook paper to live her entire life. In these crowded conditions, they are unable even to spread their wings." This is the type of living conditions that McDonald's board of directors seems to think is appropriate for the chickens that produce the eggs used to make its meals in the U.S.
