All the other threads show places where you can run around and pick up like 5 eggs. Forget that, Kharanos is in Dun Morogh. Dun Morogh has Snow Bunnies all over it's zone! Thus, it's the king of eggs. Here's why:
You can stand on your little mound and move to each spot as an egg pops up. Theres almost NO downtime at all, I was getting more eggs than I had time to open. Was able to get all the items and chocolate I needed for the whole event in about 45 minutes at this spot.
Also on my server at least, Dun Morogh was the least busy. Everyone seemed to think that Teldrassil and Azuremyst would be since they are out of the way, and everyone went there and they ended up being the most busy. So you might want to /who the zones.
This is in on the north west side of town, you can see the fence along the road that leads up to IF, and a building (not the inn) on the left.
The SS shows 10 egg spawns, but also if you turn your camera 180 degrees you can see on the other side of the road that there are about 3-4 spawns that you could also grab if your side gets camped
