How to decide whether an egg is worth hatching
Use egg prediction after you have an egg and can read its height and weight. The tool narrows the candidate list, while parent compatibility and egg groups still determine what the pair can actually produce.
Recommended workflow
- Record the egg height, weight, and rideable status when available.
- Check whether your target appears in the candidate list and how many candidates remain.
- Compare the candidates with the parents and their shared egg groups.
- If the target is absent, verify the input before moving on to another egg.
Common mistakes
- A single match is still an estimate and may change with game updates.
- Before an egg exists, use the breeding matcher instead of this tool.
- A long candidate list means more parent information is needed.
