I would just say that for people that love eating eggs, if you have the space get a couple of chickens. They are about as hard to look after as rabbits, and once you have proper, fresh eggs you won't go back to store-bought.

It all depends on what they eat. Both articles actually say this, but bury it for some reason.
Hens in a barnyard eating high quality feed supplemented by insects, etc have a different flavor and texture than hens just fed feed. "Eggland's best" taste different because they are supplemented with flax.
Similar phenomena exists with beef and pork. Grass fed beef tastes different due to more Omega-3 in grass. Danish pork tastes a little different because the pigs eat fish.
Even if you don't believe they taste any different, they're interesting animals and it's a fun hobby.
