How to Get the Bone Rooster
What this page helps you decide: which egg to hatch for the Bone Rooster, and how many hatches to budget before it shows up
The Bone Rooster is a Uncommon chicken, tier 2 of 10 on the rarity ladder that appears in the drop data. One egg can hatch it, and the best published rate is 17% from the Haunt Egg — about 6 hatches before you should expect to see one. Below: every route in with the expected hatches worked out, where it sits among the 10 outcomes of that egg, how it compares with the other Uncommon chickens, and what we found when we checked the published percentages.
Only one way in
Nothing else in the current drop data produces the Bone Rooster. That makes the Haunt Egg a single gate: at 17% you should expect around 6 hatches before it appears, and farming any other egg does not shorten that number. The Haunt Egg itself is laid by the Creepy Clown, 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 Haunt Egg
The Haunt Egg can hatch 10 different chickens. The Bone Rooster is the 2nd most likely of them, with 7 outcomes sitting below it on the table. At that position it turns up often enough that a dedicated farm is usually wasted effort — it arrives while you are chasing the rarer drops in the same egg.
Against the other Uncommon chickens
There are 20 Uncommon chickens in the current drop data. Ranked by best available rate, 3 of them are easier to obtain than the Bone Rooster and 16 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 Haunt Egg table does add up, which is a small point in its favour. 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 Creepy Clown on your plot — it lays the Haunt Egg, which is the source you can actually control.
- Hatch it repeatedly and budget around 6 hatches at the published 17%.
- Do not spend sessions on other eggs hoping for it; nothing else in the data drops the Bone Rooster.
- Treat it as a by-product: farm the Haunt Egg for its rarer outcomes and this one will arrive on the way.
