How to Get the Mecha Rooster
What this page helps you decide: which egg to hatch for the Mecha Rooster, and how many hatches to budget before it shows up
The Mecha Rooster is a Legendary chicken, tier 5 of 10 on the rarity ladder that appears in the drop data. One egg can hatch it, and the best published rate is 8% from the Circuit Egg — about 13 hatches before you should expect to see one. Below: every route in with the expected hatches worked out, where it sits among the 8 outcomes of that egg, how it compares with the other Legendary chickens, and what we found when we checked the published percentages.
Only one way in
Nothing else in the current drop data produces the Mecha Rooster. That makes the Circuit Egg a single gate: at 8% you should expect around 13 hatches before it appears, and farming any other egg does not shorten that number. The Circuit Egg itself is laid by the Taser Hen, so one of those on the plot is the entire supply chain — there is no second source to fall back on if you stop keeping it.
Where it sits inside the Circuit Egg
The Circuit Egg can hatch 8 different chickens. The Mecha Rooster is the 6th most likely of them, with 2 outcomes sitting below it on the table. At that position it is one of the outcomes you are genuinely farming for, not something that shows up on the way to something else. Plan the session around it rather than expecting it as a side effect.
Against the other Legendary chickens
There are 21 Legendary chickens in the current drop data. Ranked by best available rate, 2 of them are easier to obtain than the Mecha Rooster and 18 are harder. Rarity labels are not difficulty labels: two chickens carrying the same tag can sit an order of magnitude apart in expected hatches.
What the published table does not say
These rates come from a single community index rather than the game files, so we checked the arithmetic before using them. 9 of the 17 egg tables do not add up to 100 percent — across the set they run from 91 to 102 percent. The Circuit Egg table is one of those, summing to 101 percent, so treat 8% as a rounded figure rather than an exact one. Rounded rates are good enough for deciding which egg to farm. They are not good enough for predicting any single hatch, and anywhere a rate is written as "under 1%" the true value could be several times smaller than the estimate above.
Step-by-Step
- Keep a Taser Hen on your plot — it lays the Circuit Egg, which is the source you can actually control.
- Hatch it repeatedly and budget around 13 hatches at the published 8%.
- Do not spend sessions on other eggs hoping for it; nothing else in the data drops the Mecha Rooster.
- Treat it as the target of the session; at 6th of 8 it will not appear as a side effect.
