Grow a Chicken Fighter Fuse Guide: Locks, Costs & Recipes
Fusing is how you move a skill or an egg-laying trait from one chicken onto another, and it is the only way to build the meta birds. Get the lock step wrong and you burn a rare donor for nothing, so read the lock section before you press confirm.
How a fusion works
- Open the Fuse menu, pick the chicken you want to keep (the base), then pick the donor. The donor is consumed and the fusion is permanent.
- It costs Cash, and the price climbs every time you fuse. In one recorded first-day run the first fusion cost $91 and a later one about 2.1K; your prices will differ with rebirth count and how many fusions you have already done.
- The tutorial forces one fusion early (“You will need two chickens”), so you will see the menu within your first ten minutes.
- Standard routine used by players who fuse a lot: pick the keeper, add the donor that has the skill or trait you want, lock that target, read the rest of the preview, confirm, then check the card afterwards.
What carries over
| Thing | What happens | Notes |
|---|---|---|
| Stats | The higher max of each stat wins | One player fused a 4/27 stat with an 11/27 and got 11/27 |
| Rarity | Can go up | An uncommon to rare jump was recorded in one early run |
| Level | Resets unless you lock it | Footage shows a high-level bird dropping back to level 18; other players report locking the level keeps it |
| Skill | Re-rolled unless locked | A player aiming for Rebirth ended up with Event Horizon because the skill was not locked |
| Laying trait | Can be moved to the base and locked | This is how multi-egg layers are built |
| Look (hat, colors) | Lockable | Cosmetic only |
| Inverted | Can transfer | Community reports put it around 2–33% after the Aug 15 hotfix, down from about half before |
Lock slots and the fusion gamepasses
By default you get two lock slots (reported by players, not an official figure). Everything else in the preview is fair game for the re-roll. You can lock a skill, the level, the cosmetic look, or the laying trait; to release a lock you press X on it and tap again.
The official store sells extra slots:
| Pass | Price | Store text |
|---|---|---|
| Fusion Lock 3 | 99 R$ | unlocks lock slot 3 |
| Fusion Lock 4 | 149 R$ | unlocks lock slot 4 |
| Fusion Lock 5 | 249 R$ | unlocks lock slot 5 |
| Fusion Lock 6 | 399 R$ | unlocks lock slot 6 |
| Fusion Lock 7 | 599 R$ | unlocks lock slot 7 |
| Fusion Lock 8 | 899 R$ | unlocks lock slot 8 |
| Fusion Master | 1,199 R$ | “all six fusion lock slots at once” |
| King of the Coop | 1,499 R$ | x2 corn, x2 money, half-price elevator, all six lock slots |
The store text says “six” slots for the bundles while the single passes run up to slot 8; we report both as written. If you only ever need one skill plus one laying trait, the free two slots are enough. The full pass list is on the gamepasses page.
Moving egg-laying traits
The laying trait is the second thing worth locking. One player moved a 100% Thunder laying trait onto another chicken, and a repeated-fusion build produced an Astro Chick that lays Void, Nest, Thunder, and Scratch Eggs, one every 4 minutes (one recorded build, so treat the timer as that player’s result). Stacking several Zombie Chicks into one is the standard trick for faster Haunt Egg laying. Stacking Founder Roosters did not raise their 30% egg fertility in one player’s test.
Rarity and the stat cap
The 31 stat cap is only reachable on cosmic and secret chickens, and a fusion that lands in that tier gets the 31 cap. Lower tiers cap out earlier (27 in one example). See the rarity list for the ladder.
Recipes players actually run
| Base | Donor | Lock | Result |
|---|---|---|---|
| Reaper Rooster | Doll Hen | Voodoo | The Voodoo Reaper, the most-copied build; full steps in the Reaper x Voodoo guide |
| 404 Chick | Radiant Fenghuang | Cycle of Ash | S-tier speed bird; one recorded result kept the Fenghuang look |
| Reaper Rooster | Nebula Hen | Voodoo (already on base) | Higher-HP Voodoo carrier, one creator’s endgame build |
| Phoenix Hen | Doll Hen | Level 56 on Phoenix + Voodoo | One recorded fusion that locked both a level and a skill |
When not to fuse
- Only fuse a donor that adds something the base does not have: a better stat max, a skill, or a laying trait.
- Check the laying trait before selling or feeding duplicates; a boring-looking chicken can lay the egg you need.
- Do not fuse two good skill carriers together without locking, because you can lose both skills.
- Fusion is not the only way to grow a bird; feeding and fighting raise levels, see how to upgrade chickens.
