My experience is about 1 hr of farming with 25 to 35 kills for one. I am working on trying to get my second right now.
I went back and farmed more bones. Taking into account bones from when I originally started and assuming an average drop rate of 8 bones per kill for a direhorn hatchling. It works out to a drop rate for me of 1 in 26.
