The lightweight 'news' and magazine TV programme, Today Tonight ran a piece about US researchers claiming to demonstrate that there is no nutritional difference between free range and cage laid eggs.
Of course the study undertaken by North Carolina State University showed there was no difference. The research was funded by the egg industry and the hens used were all beak trimmed.
The 'free range' hens used in the research programme may have been allowed access to the outdoors, but as their beaks were trimmed, they essentially could only eat the same grains and food which were available to the birds in cages. They had great difficulty eating grass, or picking up worms, spiders etc without a full beak.
TV shows like this just perpetuate the myth that 'an egg is an egg'.
