What does rebirth do in Grow a Chicken Fighter?

Rebirth trades your current run for a permanent bonus that speeds up the next grind. It resets progress but the multiplier carries forward, so each rebirth makes the following one arrive sooner.

What do you need before rebirth in Grow a Chicken Fighter?

Bank a Nest Egg or your fastest rebuilding source first, read the permanent bonus in the rebirth panel, and only reset when that bonus makes the next pre-spike grind meaningfully faster.

What carries over after rebirth?

The permanent multiplier carries forward. Saved Nest Eggs and idle eggs let you redeploy a fighter immediately after the reset, restarting the money loop from a higher floor.

How many times should you rebirth?

As many times as a reset keeps speeding up your climb. Realistic targets are covered in our how-many-rebirths guide; reset for the bonus, never because a run stalled.

Rebirth Requirements & Rewards in Grow a Chicken Fighter

1. What does rebirth do?

Rebirth resets your run and hands you a permanent bonus that speeds up the next grind. You lose current progress — fighters, upgrades, floors — but the multiplier compounds across resets. That's the whole trade: a run now for a faster run later. The full when-to-reset guide covers the timing; this page focuses on the conditions and payouts.

The one-line answer

4. The post-rebirth reset checklist

Bank a Nest Egg (or your fastest rebuild source) — rebirths feel brutal when your egg economy starts from zero. See how to hatch eggs for the economy basics.
Hatch instantly after reset, slot your best early fighter into the PIT, and reapply the feeder-first upgrade order from the beginner guide.
Track the trend in the resource calculator — when the pre-rebirth spike time stops shrinking, the bonus is done doing its job and it's time to push tower floors instead.

There's no published cap. The practical stop is when a bonus stops speeding up your climb — see how many rebirths for the cadence reasoning.
