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

ThingWhat happensNotes
StatsThe higher max of each stat winsOne player fused a 4/27 stat with an 11/27 and got 11/27
RarityCan go upAn uncommon to rare jump was recorded in one early run
LevelResets unless you lock itFootage shows a high-level bird dropping back to level 18; other players report locking the level keeps it
SkillRe-rolled unless lockedA player aiming for Rebirth ended up with Event Horizon because the skill was not locked
Laying traitCan be moved to the base and lockedThis is how multi-egg layers are built
Look (hat, colors)LockableCosmetic only
InvertedCan transferCommunity 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:

PassPriceStore text
Fusion Lock 399 R$unlocks lock slot 3
Fusion Lock 4149 R$unlocks lock slot 4
Fusion Lock 5249 R$unlocks lock slot 5
Fusion Lock 6399 R$unlocks lock slot 6
Fusion Lock 7599 R$unlocks lock slot 7
Fusion Lock 8899 R$unlocks lock slot 8
Fusion Master1,199 R$“all six fusion lock slots at once”
King of the Coop1,499 R$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.

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.
