It was probably never lubricated after leaving the show room, being exposed to elements such as water, dust, dirt it will wear the chain out and grind down the sprockets sooner/easier. When lubricated every thousand or so miles, the metal on metal contact wear is alleviated and moves much more freely...my chain was like your when i got my bike, very stiff and did not move much and almost clicked. So i spent 20 minutes cleaning it and rinsing off the build up, sprayed it with a general oiler and then a true chain grease and its worked great since.
