Data and results of an experiment I did with hatching different eggs

These are my results from hatching 5 of each different egg. (yes my buck balance is suffering)

Cracked Egg:

• Mouse (Common)
• Mouse (Common)
• Donkey (Uncommon)
• Poodle (Uncommon)
• Parakeet (Rare)

Pet Egg:

• Ant (Common)
• Ant (Common)
• Donkey (Uncommon)
• Poodle (Uncommon)
• Alicorn (Legendary)

Moon Egg:

• Hopbop (Common)

• Snorgle (Uncommon)

• Zeopod (Rare)

• Moonpine (Rare)

• Moonpine (Rare)

If we assign 1 point to a common, 2 points to an uncommon, 4 points to a rare, 8 points to an ultra rare, and 16 points to a legendary...

Based on these results:

• The Cracked Egg has an efficiency of 0.0286 points per buck
• The Pet Egg has an efficiency of 0.0367 points per buck
• The Moon Egg has an efficiency of 0.0200 points per buck

So the Pet Egg is the best of the three eggs, but this might be due to getting an Alicorn.

I would still recommend this egg for growing your inventory!
