If everything has a purpose then evil doesn't exist

Such a hot steaming pile that just keeps growing.  

The easter bunny went to ark and dropped off eggs that didn't need to be incubated.

are you familiar with how mulch is made?

In this mulching process bacteria breaks down generally plant matter and in this process the mulch pile can internally reach temps as high as 160*F the closer you get to the center of the pile. an egg only needs about 100*F to incubate.

Noah would have need quite a large amount of hay to feed whatever dairy animals he had to keep all the baby mammals alive. which also means plenty of poop/the caytlist for mulch.

So it is all very plausible, as all the resources were there to incubate said eggs.
