The published rates do add up

Adding every listed chance on this egg gives exactly 100 percent, which is a point in this table's favour: 9 of the 17 tables in the same index do not, ranging from 91 to 102 percent. That makes the ordering below trustworthy even if individual figures are rounded.

What the ceiling is worth chasing

The rarest thing this egg produces is the Comso Brat, a Uncommon at 100%. That works out to roughly 1 hatches before you should expect one. It is the only Uncommon on this egg, so a long session has exactly one payoff worth naming. Every chicken on this egg can also be reached through at least one other egg, so this is a convenience route rather than a mandatory one.

Where this egg sits in the chain

The Grudge Egg is not laid by any chicken: Currently unobtainable. That makes supply, not drop rate, the thing that limits it. None of its outcomes lay eggs themselves, so this egg is an endpoint rather than a step toward another one.

Step-by-Step

  1. Secure the egg first: Currently unobtainable. Everything else here is downstream of that.
  2. Decide what you are farming for. The ceiling is the Comso Brat at 100%, about 1 hatches.
  3. Remember every outcome here is reachable elsewhere too, so compare rates before committing a session.
  4. The percentages here do sum to 100%, so the ordering is safe to plan around.
