Found a shared spreadsheet of where which mouse drops what eggs..
It'll be updated as each daily egg is found.
The Egg Spreadsheet.
And if you're the "fire and forget" type of player, just plant yourself at the Catacombs - currently the only place to get 2 types of eggs (Green Plaid + Blue Argyle).
[Apr 18 update] Newer eggs are appearing in the higher level areas.. I do hope that there's still something for everyone by the Easter weekend.. :p
