Void Eggs are pitch-black eggs in Grow a Chicken Fighter that hold ten space-themed fighters, including two of the strongest Arena picks: the Void Rooster and the Nebula Hen. You collect them by keeping the right chickens in your coop or the Egg Incubator, which opens after you complete Rebirth 3. The fastest path runs through the Thunder Egg line, so most players reach Void Eggs in the mid-game rather than at launch.
Quick answer: Hatch a Static Chick from a Thunder Egg, farm Thunder Eggs until you get an Astro Chick (30% chance), then deploy the Astro Chick. It lays a Void Egg 70% of the time, the highest Void Egg drop rate in the game.

Ten chickens can lay Void Eggs. The Astro Chick is the strongest early option, while the Void Rooster is the goal once you can hatch one. The rest supply Void Eggs at lower rates and are worth keeping if you already own them.

Void Rooster: the 100% Void Egg layer
The Void Rooster is a Mythic-rarity chicken that lays a Void Egg every 7 minutes at a 100% rate. That makes it the most efficient long-term farm once you own one. The Fertility Gene shortens its egg-laying timer, so a rooster with that gene produces Void Eggs faster.
Merging a Void Rooster with a duplicate Void Rooster also cuts down its egg-laying time. If you fuse an Astro Chick with a Void Rooster instead, the resulting chicken gets a better chance of producing Void Eggs. Both routes improve your steady output, so pick based on which duplicates you have available.

What hatches from a Void Egg
Opening a Void Egg gives one fighter from a pool of ten. The Void Rooster and Nebula Hen are the standout pulls thanks to their low odds and strong combat abilities.
| Chicken | Rarity | Hatch chance |
|---|---|---|
| Probe Rooster | Common | 25% |
| Moonwalk Hen | Uncommon | 19% |
| Solar Rooster | Rare | 14% |
| Little Green Chick | Epic | 8% |
| Comet Rooster | Epic | 8% |
| Orbital Hen | Epic | 8% |
| Singularity Hen | Epic | 8% |
| Astro Chick | Legendary | 5% |
| Void Rooster | Mythic | 3% |
| Nebula Hen | Cosmic | 1% |
The Void Rooster carries the Event Horizon skill. When triggered, a line forms around the pit, and any opponent that crosses it takes heavy damage and knockback. The Nebula Hen uses the Stardust skill, filling the air with particles that lower the attack speed of nearby enemies. The Nebula Hen can also lay Void Eggs, so pulling one adds another layer to your farm.
How to hatch Void Eggs
Open your inventory, select the Void Egg, and press the yellow Hatch button. You can hatch up to 10 Void Eggs at once, which speeds up the grind toward rare pulls like the Nebula Hen at 1%. Every chicken you hatch from a Void Egg can be fused, so duplicates are useful as fusion material rather than dead weight.
If Void Eggs never appear, the usual cause is missing the entry point. You need the Thunder Egg line running to reach the Astro Chick, and the Egg Incubator unlocks only after Rebirth 3. Confirm both before committing to a long farming session, then let the Astro Chick or a Void Rooster keep the eggs coming.
