Grow a Chicken Fighter Incubator Guide: Unlock & Best Pick
The Incubator is the biggest quality-of-life addition from Update #1: one chicken goes in, eggs pile up while you fight, and you claim them in a batch. Here is what it costs, how to level it, and which chicken actually belongs inside.
What the incubator does
- You place one chicken in the slot. That chicken decides which eggs the incubator can produce, exactly like its normal laying trait.
- Eggs stack in a storage bank until you press Claim. Storage is upgradable, so you can leave it running while you climb the tower or fight in the pit.
- A luck boost builds up the longer you stay on the same server. The number players report is about 90 minutes in one server for +10% luck on rarer eggs (single-source, from recorded runs).
- Your regular coop still holds eggs too (one player counted a 14-egg coop cap), so the incubator is extra capacity, not a replacement.
Whether it keeps producing while you are offline has not been confirmed by anyone we trust, so plan around being online.
Unlock cost and upgrade path
| Step | Requirement / effect | How solid is this? |
|---|---|---|
| Unlock | 300,000 Cash | Reported in recorded play; one guide adds “Rebirth 3 or higher” (single source) |
| Storage upgrades | Storage grows with each level; one player’s level 15 incubator held 54 eggs, another source puts the max at 60 eggs | Numbers differ between sources; treat both as reported |
| High levels | Some upgrade levels are gated behind Rebirth 75 | Single source, but repeated by two creators |
| Lay timer | Founder Rooster ≈ 4:39 per egg at base; ≈ 1:37 reported at a high incubator level | Single recorded run each, so expect variation |
300,000 Cash is a mid-game number. If you are still under a few rebirths, spend the money on feeders and the recycler first (see how to get money fast) and come back for the incubator once tower floors pay five figures.
The rebirth problem
Two things happen when you rebirth with the incubator running:
- Your luck boost resets. The boost also drops if you hop servers, so a private server you never leave is the safest way to keep it (see private servers).
- The chicken inside can get removed. Hotfix 1.1 on August 15 listed a fix for the incubator chicken being removed on rebirth, but players were still reproducing the bug on August 16. Until that is clearly fixed, claim your eggs and take the chicken out before every rebirth. If you rebirth often (high-rebirth players do it every couple of minutes), that habit matters more than any upgrade. More on cycle timing in the rebirth guide.
Which chicken to put in the incubator
Pick by the egg you want, not by who hits hardest. The whole point is the egg stream.
| Goal | Chicken to use | Why |
|---|---|---|
| Colossal Egg (Storm Colossus, Talon Titan, Shockwave Hen, Rumble Rooster, Dudoo Squat) | Founder Rooster | The only non-event Colossal source: about 25% of its lays are Colossal, with the rest split between Royal and Fortune |
| Fortune Egg (Founder Rooster, Baron Cluck, Golden Goose 1%) | Baron Cluck | Lays Fortune 100% of the time; Founder Rooster also gives Fortune but only half its lays |
| Haunt Egg (Doll Hen ~2%, Reaper Rooster under 1%) | Zombie Chick | Haunt 100%, roughly every 2 minutes; this is the Voodoo grind |
| Cursed Egg (404 Chick under 1%) | Stone Face | Cursed 100%, about every 2 minutes, faster with rebirth buffs |
| Royal Egg (Radiant Fenghuang, Phoenix Hen, Valkyrie Hen) | Rooster of Fortune | Royal 100%; Crest Rooster is only 60% |
A few notes from recorded runs:
- Fusing several Founder Roosters together did not raise its egg fertility stat in one recorded test, so do not burn copies expecting more eggs.
- Founder Rooster is not a single-egg chicken (Royal 50% / Fortune 50% normally, plus the Colossal share in the incubator), so expect a mix when you claim.
- The egg index shown before a hatch reflects your current state, and some players believe rarer eggs get better pools as your recycler and rebirth count climb. That is why high-rebirth players chain incubator claims right before opening.
Quick setup checklist
- Farm 300,000 Cash (and reach rebirth 3 if your server shows that gate).
- Decide on the egg you are hunting, then drop in the matching chicken from the table above.
- Stay on one server to build the luck boost; private servers help.
- Claim eggs before each rebirth and pull the chicken out until the removal bug is confirmed dead.
- Once Rebirth 75 is in reach, push storage levels for longer unattended runs.
For every egg pool and who lays what, use the egg index; for the patch history behind the incubator, see the update log.
