Grow a Chicken Fighter 404 Chick & Cursed Eggs

The 404 Chick is a secret Grow a Chicken Fighter pull that does not drop from a starter Nest spam. You climb a Cursed Egg chain: each chicken unlocks the next shell until a leveled Stone Face turns the grind into a repeatable AFK loop. This guide summarizes the community chain (Classic Rooster → Cosmo Brat → NPC Chick → Stone Face → 404) so you do not sell the wrong bird mid-route.

What to know before you start

• 404 Chick comes from Cursed Eggs, not from Thunder or Void shortcuts. Some indexes also list a Blazing Egg hatch near 8% versus Cursed well under 1%—Hot Event or a live 40KCCU redeem can be the faster hunt (Events, Codes).
• Once hatched, several catalogs give 404 100% Cursed lays, so the secret can feed the next copy instead of replacing Stone Face on day one.
• You need several chicken tiers first—rushing Cursed without Cosmo/NPC wastes hours.
• Cosmo Brat (Uncommon) is the Scratch engine; reports cite 100% Scratch lays.
• NPC Chick farms Cursed at roughly 80% until Stone Face arrives.
• A leveled Stone Face can approach one Cursed Egg per minute, which is the real farm setup.
• Percentages and timings are community-reported (mid-August 2026). Verify in your Flock UI after patches (What’s new).

Full sentence form: Classic Rooster → Nest Eggs → Cosmo Brat → Scratch Eggs → NPC Chick → Cursed Eggs → Stone Face → 404 Chick.

Step 1 — Nest Eggs and Cosmo Brat

Deploy Classic Rooster in the coop and collect Nest Eggs in batches—not one-at-a-time panics. Hatch Nest Eggs until you pull Cosmo Brat. Code Nest Eggs from WELCOME can accelerate this (Codes, Egg routes). Do not sell Classic Rooster until Cosmo is secured if Nest volume is still your bottleneck.

Step 2 — Scratch farm with Cosmo Brat

Swap Cosmo into the laying slot. AFK or multitask PIT while Scratch Eggs stack. Open Scratch Eggs until NPC Chick appears. Cosmo’s job is Scratch volume; do not fuse Cosmo away for a vanity craft unless you already have a duplicate route bird (How to fuse).

Step 3 — NPC Chick → first Cursed Eggs

Deploy NPC Chick. Community reports put Cursed chance near 80%. Build a stockpile, then hatch toward Stone Face. Mixing tiny hatch sessions with constant UI clicking makes the hunt feel worse—batch when you can.

Step 4 — Stone Face is the farm, not a trophy

Once Stone Face lands, upgrade/level it and park it for Cursed production. This is the efficiency spike: leveled Stone Face roughly guarantees a Cursed Egg about every minute in community testing. Stop relying on NPC Chick’s 80% loop for the long grind.

Step 5 — Mass hatch for 404

AFK Stone Face, bank dozens or hundreds of Cursed Eggs, then open in batches. The secret 404 Chick is a Cursed hatch target—there is no skip button. Keep PIT Cash flowing between hatch waves so feeder/attack do not stall (Make money fast, Feeder and recycler).

Efficiency habits

1. Replace farmers on purpose — Classic → Cosmo → NPC → Stone Face. Do not cling to nostalgia birds.
2. Check Flock before selling — selling Cosmo or Stone Face early resets days of progress (Sell chickens).
3. Batch eggs — stockpile, then hatch sessions.
4. Use offline laying — arm the coop when you quit so Nest/Scratch/Cursed progress continues (Eggs offline).
5. Friend boosts — when you return for PIT Cash between AFK blocks, invite friends if the boost is available.
6. Chaos / Hot events — interrupt only if event eggs beat the current chain goal (Events).

What 404 is for

After you own 404, the community late craft is 404 x Ash: farm Radiant Fenghuang from Royal Eggs (Crest → Rooster of Fortune) and lock Cycle of Ash before confirming. Do not fuse Stone Face into that craft.

Safety and scam watch

No one needs your password to “inject 404.” Fake Discord bots, “private cursed scripts,” and lookalike Chicken Farm tools are risks—not shortcuts (Scripts, Script safety, Similar games). Confirm place 94640181989498 and Sergio Verse Games before trusting any download.

Climb the chain once the right way. Stone Face turns Cursed hunting from a lottery into a farm—404 is just the hatch at the end of that farm.
