The Nebula Hen ranks among the strongest fighters in Grow a Chicken Fighter, sitting alongside the Reaper Rooster and 404 Chick at the top of the meta. Its one weakness is a slow start, and the fix is pairing it with the Cycle of Ash skill. That skill belongs to the Radiant Fenghuang, so the build comes down to hatching both chickens and fusing them the right way.
Quick answer: Hatch a Nebula Hen (from Void Eggs) and a Radiant Fenghuang (from Royal Eggs), open the fusion menu, and lock the Cycle of Ash skill before confirming so it transfers to the fused chicken.
What the Nebula Hen x Cycle of Ash fusion needs
Two chickens go into this build, and each one comes from a different egg chain. The table below shows what to farm and how likely each hatch is.
| Chicken | Main egg | Hatch chance |
|---|---|---|
| Nebula Hen | Void Egg | 1% |
| Radiant Fenghuang | Royal Egg | 1% |
Both chickens can also drop from the Blazing Egg, which appears during the Hot Event. The Nebula Hen even has a slightly better 2% chance there compared to the 1% from Void Eggs. Blazing Eggs are hard to farm, though, so the standard egg chains below are the more reliable route.
How to get the Nebula Hen
The Nebula Hen sits at the end of a Void Egg chain that starts with a common beginner egg. The full path runs Scratch Egg → Sergeant Hen → Thunder Egg → Astro Chick → Void Egg → Nebula Hen.
How to get the Radiant Fenghuang
The Radiant Fenghuang carries the Cycle of Ash skill and comes from Royal Eggs. The path runs Scratch Egg → Crest Rooster → Royal Egg → Rooster of Fortune → Royal Egg → Radiant Fenghuang.
Fusing the two chickens and locking Cycle of Ash
With both the Nebula Hen and the Radiant Fenghuang in your flock, head to the Fusion Menu. Select the two chickens, then lock the Cycle of Ash skill before you confirm.
Locking the skill is the step that matters. Without it, the fused chicken can roll a different ability at random instead of keeping Cycle of Ash. Once locked, confirm the fusion.
You know it worked when the fused Nebula Hen shows Cycle of Ash as its active skill in the flock. That combination smooths out the Nebula Hen’s slow early game and turns it into one of the game’s top-end builds, with attack and speed on par with the Reaper Rooster and 404 Chick and higher HP at max level.
