I liked the pairing up part a lot. It was easy to find others to do the quest with, and it added a bit of social to the event.

The spriggans on the other hand... It might have been me reading through the quest text too fast, but I never really got that I was supposed to look for spriggans (I knew fron others).

Sadly, I never even saw one.
I was working on various hunting logs and traveled all over the place, but not a spriggan in sight.

Maybe an actual egg hunt would be better? And not with respawning eggs (because they would get camped), but so that only you would be able to see them, just like the items you pick up for various quests.
