The Dragon did not hatch from the mountain. It was sleeping in the mountain. Considering its size, I'm pretty sure it's a very, very old Grimm. Grimm get bigger as they age.

This is evidenced by the small Nevermores (birds) that Blake shot down in Search and Destroy while Oobleck was asking the girls why they want to be Huntresses, as well as by the large Ursa that attacked Cardin.
