Rebirth is the prestige loop in Grow a Chicken Fighter. It wipes most of your current run in exchange for permanent bonuses that make every future run faster. The fastest way through it is to climb the tower to the exact floor the game asks for, empty your Cash into useful upgrades first, then confirm the reset. Your flock stays with you, so you rebuild quickly.
Quick answer: Send your strongest chicken up the tower until it reaches the floor listed in the Rebirth menu, spend all remaining Cash on hatching and fusing, then press the Rebirth button on the right and confirm. Your player level drops to 1, and your coop resets, but your chickens and stacking bonuses stay.
The one requirement to unlock Rebirth
Rebirth becomes available only after your Chicken Fighter climbs the tower to a specific floor. The exact floor is shown inside the Rebirth panel, and it moves as your progress changes, so always read the number on your own screen before committing. The tower is the gate. Everything else is preparation to get there.
Until you hit that floor, the Rebirth button will show a “NOT YET” state instead of letting you reset. Once you clear the required floor, the button becomes active, and the confirmation menu opens.
Prepare your chicken to climb faster
Reaching the required floor quickly comes down to keeping your best fighter alive and strong. A knocked-out chicken stops your climb, so the goal is to avoid that entirely while pushing higher.
Tip: If your climb stalls at a certain floor, return to farming and fusion to build a stronger fighter rather than throwing the same team at the same wall repeatedly.
Spend your Cash before you confirm
Rebirth sets your Cash back to zero, so any money you are holding at the moment of reset is lost. The way to avoid wasting it is to convert it into permanent progress right before you press the button.
Pour your remaining Cash into hatching eggs and fusing chickens. Both add to your flock or improve your fighters, and neither is undone by the reset. Fusing weaker duplicates into stronger, mutated chickens is a strong use of that last stretch of money, since those fighters carry into your next run and help you re-climb the tower faster.
Perform the Rebirth
You know it worked when your player level returns to 1, your coop reverts to its starting state, and your Cash resets. The Rebirth counter increases (for example, from Rebirth #0 to #1), and your permanent bonus values update.
What resets and what stays
Knowing exactly what survives a Rebirth is what makes the fast rebuild possible. Your chicken collection is the anchor that lets you power back up quickly.
| Resets on Rebirth | Kept after Rebirth |
|---|---|
| On-hand Cash (back to zero) | Your full chicken collection (flock) |
| Player level (back to 1) | Permanent Cash and Corn bonuses |
| Coop progress (back to start) | Increased Egg drop rate |
| Current-run tower and feeder progress | Higher maximum level cap |
The permanent bonuses you gain
Every Rebirth grants permanent, stacking boosts that apply to all future runs. These are the reason a reset makes you faster rather than weaker over time.
- Cash earnings boost, shown as increments such as +25%.
- Corn earnings boost, also stacking in steps like +25%.
- Higher Egg drop rate, which grows as you rebirth more.
- A raised maximum level cap, for example lifting the cap from level 10 to 12.
Because each of these stacks with every subsequent Rebirth, the compounding effect is large. The higher level cap also matters directly, since it lets your fighters surpass their previous ceiling and push deeper into the tower on the next run.
When to Rebirth for the fastest runs
Rebirth the moment it becomes available and worthwhile, especially once your current run has slowed. A clear signal is when the next meaningful upgrade takes far more farming than the upgrades before it. At that point, the permanent multiplier returns more value than grinding the same run.
After the reset, rebuild your coop, level a strong chicken again, and climb back up. Each cycle should reach your previous point faster than the last, thanks to the stacked bonuses. That loop of hatch, fight, fuse, climb, and rebirth is what carries you toward the endgame, and it can be reached without premium purchases. You can launch the game from its official Roblox page to check the live Rebirth requirement on your own account.
