On page 7 they posted a list of entries so far, so I think they're probably keeping an updated list somewhere. Also a list of how many eggs were set by who so they can track them down for hatch rates for another competition.
They don't have the answer yet, people are still setting eggs for the easter hatch along.
They're also making a list of everyone's guesses, 1 guess per person, no edits, and whoever is closest when this closes wins.
