But should we care, an egg laid in a cage tastes the same as one laid in the field? Do hens actually feel pain and are they uncomfortable in cages?
Depends on who you listen to and who you believe.
Those who have put the microscope between a hen's eyes say they actually experience rapid eye movement, which apparently means they dream, they're protective and mother their chicks, when an egg's allowed to hatch, but most importantly they have pain receptors which means they can feel pain and suffer from distress.
But for those at the top of the political pecking order, there doesn't seem to be a great deal of pity for them.
Andrew chicken Little sounded as though he thought the sky was going to fall in when he was being asked about eggs on his way into caucus, seemed as unsure about the difference between a caged egg and a free range one as he is about the political centre ground.
Little accepts he could be seen as eggnostic, saying he doesn't make a study of eggs when he does the supermarket shopping.
And the acting Prime Minister Paula Bennett, wasn't much better, admitting to deliberately buying caged eggs at times because she's known for her bacon and egg pies and a batch of half a dozen take a lot of the cheaper whites and yokes.
With her recent pay rise you wouldn't think it'd be a factor!
