Log two pals. Read the egg before it hatches.
Pick a pair, set who's carrying, and Hatchlog runs the same rank-averaging the game uses — plus every documented special pairing — so you know what's coming before you spend a cake on it.

Parent B
Reading the result
Formula result means the offspring came from averaging both parents' breeding ranks. Special combo means this exact pairing is hardcoded to a fixed outcome, overriding the formula entirely. Same species means two of the same pal were paired, which always breeds true.
Didn't get what you expected?
Working toward a specific pal instead of checking a pair you already have? Use Breeding Path to search forward from pals you own, or Breeding Tree to explore parent options backward from your target.
