Exiting ! Hooray for polls :D
A mix of option 1 and 3 : 2 diff chests, one with and the other without the hatching, while still being able to get just the hatching.
Maybe even a fourth option, a bundle with 2 hatchings for people who wants evo + non evo of the pet ? (not the past bundle of 3 hatchings, this made no sense)
