Egg Calculator & Hatch Explorer
Choose an egg to see its documented pet pool, sorted by rarity, with a base rate only where sources publish one. The official Roblox game page establishes the hatch-and-collect loop; IGN's All Pets guide and the listed egg references support the pool entries.
Rift Update event egg paid out by The Rift while the Riftbeasts banner is the Current Egg (35% displayed rotation chance), and by Boss Mastery at 10 kills. Hatches one of five Void-themed Rift pets at displayed chances of 45% / 36% / 15% / 4% / 0.5%.

FAQ
Questions players ask about eggs.
What are the hatch odds for each pet?
Most eggs still have no published rate table, so percentages stay blank rather than presenting an unsupported estimate as a rate. Rift Eggs are the exception: their chances are displayed in-game (45/36/15/4/0.5%) and shown on those pools exactly as displayed.
How often do eggs respawn?
Independent guides report that nest eggs reset on a 4.5-minute night cycle. Giant and Secret event timing is reported as irregular, so this tool does not calculate a universal rare-egg schedule.
Do bigger eggs give better pets?
Yes — larger and more 'exotic' egg variants that spawn next to a biome's parent pets have better odds of high rarity pets and mutations, according to IGN's guide.
How do I use the Steal An Egg Egg Explorer?
Choose an egg to view its documented pet pool, rarity, and base-income evidence. From a listed pet, jump to the income calculator to run explicitly labeled mutation comparison settings.
Why are some egg results marked unknown?
The explorer separates documented pools from unverified facts. A missing percentage or income means the developers have not published it or sources do not agree yet — it is not an assumed zero.
