Let's check your pickings. :)
A3, D9, G6, J10, H4

Congrats! You have found 2 blue eggs on A3 & D9 and 1 colored egg on G6.
H4 was already been chosen by another player.

Aktueller Stand: !dubby 8 % (+ XX % Gruppenbonus für nicht gefundene Ostereier :) )
I don't know what kind of bird laid the blue eggs, but they definitely exist :)
Thank you!
