How to Get the Ace Rooster in Grow A Chicken Fighter

In Grow A Chicken Fighter, dominating battles requires building the strongest lineup possible, and currently, no unit stands above the Ace Rooster. 

Considered the definitive top-tier fighter in the current meta, this elusive secret chicken brings unparalleled versatility and high-end power to your roster.

However, obtaining it is not a matter of pure luck right out of the gate. Players cannot simply open a starter crate and stumble upon this unit.

Unlocking the Ace Rooster demands an extensive multi-tier breeding and hatching chain, beginning all the way down with basic starter birds.

If you want to know how to navigate each breeding tier, optimize your drop rates, hatch Trick Eggs, and unleash the full potential of fusion, here is everything you need to know.

The Complete Ace Rooster Progression Chain

Before diving into the detailed breakdown of each step, review the full chain required to transition from your basic coop chickens up to the final secret fighter:

• Classic Rooster produces Nest Egg

• Nest Egg hatches Viking Rooster

• Viking Rooster produces Thunder Egg

• Thunder Egg hatches Founder Rooster

• Founder Rooster produces Colossus Egg (25% drop rate)

• Colossus Egg hatches Catalyst Hen (<1% hatch rate)

• Catalyst Hen produces Trick Egg (2% drop rate)

• Trick Egg hatches Ace Rooster (<1% / ~0.5% hatch rate)

Step 1: Laying the Groundwork with Nest Eggs and Viking Roosters

Every journey toward top-tier birds begins at the bottom of the ladder. To start your journey, your primary focus is working with the Classic Rooster.

When placed in your setup, the Classic Rooster yields Nest Eggs. Gather these eggs and hatch them continuously until you secure the Viking Rooster.

The Viking Rooster serves as your initial progression milestone, transitioning your operation out of the beginner tier and preparing your farm for elemental egg production.

Step 2: Farming Thunder Eggs for the Founder Rooster

Once you have secured the Viking Rooster, set up your space to start generating Thunder Eggs.

Thunder Eggs require consistent incubation. Your target pull from this tier is the Founder Rooster.

The Founder Rooster represents your first major gatekeeper unit. It is the very first bird in the game capable of producing Colossus Eggs.

Keep hatching your Thunder Eggs until the Founder Rooster is safely in your collection before moving forward.

Step 3: Farming Colossus Eggs and Hatching the Catalyst Hen

With the Founder Rooster unlocked, your operation shifts into high gear. The Founder Rooster comes with a 25% chance to yield a Colossus Egg.

While a 1-in-4 probability is relatively generous compared to later stages, you will still need a large quantity of Colossus Eggs due to the extremely low hatch rates of the bird inside.

How to Speed Up Colossus Egg Farming

To maximize your egg output:

• Deploy your roosters both inside your active coop and into the Egg Incubator simultaneously.

• Combining your coop slots with active incubator placement ensures you farm Colossus Eggs at the fastest possible rate.

• Stockpile dozens, if not hundreds, of Colossus Eggs before starting a mass hatching session.

The Catalyst Hen Hurdle

Once your Colossus Eggs are stacked, begin hatching them. Your goal here is the Catalyst Hen.

Be prepared for a grind: the Catalyst Hen features a hatch rate of below 1%. You may need to hatch several dozen batches before seeing one emerge.

Patience is critical during this phase, as the Catalyst Hen is required for the final egg tier.

Step 4: Grinding Trick Eggs with the Catalyst Hen

The Catalyst Hen is the sole bird responsible for giving you Trick Eggs. However, generating these eggs is one of the steepest bottlenecks in the entire game.

A Catalyst Hen has only a 2% chance to drop a Trick Egg.

Because of this slim 2% yield rate, passive farming with a single bird will feel painfully slow.

Just as in the previous step, place your Catalyst Hen across your farm coop and in the Egg Incubator at the same time. Stacking every available slot ensures that every roll counts toward triggering that 2% Trick Egg drop.

Do not attempt to hatch Trick Eggs one by one as soon as you find them. Build up a substantial reserve so you can commit to dedicated opening runs.

Step 5: Hatching Trick Eggs for the Ace Rooster

The Trick Egg contains five different birds, each belonging to a distinct rarity tier. Below is the complete drop table for the Trick Egg so you know exactly what to expect during your pulls:

As the drop table shows, the Ace Rooster sits firmly in the Secret category with a hatch probability under 1%, estimated around 0.5%.

Statistically, players often have to open hundreds of Trick Eggs before successfully pulling their first Ace Rooster.

If you end up pulling multiple copies of Domino Chick or Checkmate Hen, remain consistent with your Catalyst Hen farming routine.

How to Maximize the Ace Rooster with the Fusion System

Unlocking the Ace Rooster is a massive accomplishment, but hatching the bird is only half the battle.

What truly makes this unit the best bird in the game is how it interacts with the fusion mechanic.

Once unlocked, the Ace Rooster can be fused with other birds in your collection:

• Cosmetic Customization: Through fusion, the Ace Rooster can inherit the visual model and appearance of whichever chicken you feed into it, allowing you to showcase any skin design you like.

• Stat Inheritance: You can pass down optimized battle numbers, ensuring your fighter hits maximum thresholds across health, damage, and speed.

• Skill Synergy: Fusion enables you to transfer selected skills, letting you tailor the ultimate active and passive moveset tailored specifically to your playstyle.

By combining the natural baseline prowess of the Ace Rooster with high-tier donor birds through fusion, you create the ultimate competitive fighter capable of carrying you through the toughest battles in the game.
