The Colossus Egg is a special Egg in Roblox's Grow a Chicken Fighter because it can hatch the Secret Storm Colossus Chicken. Currently, there are only two ways to obtain this Egg. You can get it during the Chicken Boss Event or obtain it from Founder Rooster's Drops. In this article, we go over how you can get the Colossus Egg in Grow a Chicken Fighter in detail.
How To Get The Colossus Egg in Grow a Chicken Fighter
There are two ways to get the Colossus Egg in Grow a Chicken Fighter:
- Founder Rooster: Deploy a Founder Rooster in your Coop or use it in the Incubator to produce Colossus Eggs.
- Chicken Boss Event: Deal 1 million damage to the Chicken Boss to earn Colossus Eggs.
1. Founder Rooster Method

The Founder Rooster has a 25% chance of dropping the Colossus Egg in Grow a Chicken Fighter. You can increase the chances by adding the Founder Rooster to the Incubator. You can increase the incubation Luck by upgrading it.
Here are all the Eggs that drop the Founder Rooster:
- Thunder Egg: 3%
- Royal Egg: 6%
- Fortune Egg: 56%
- Fang Egg: 3%
- Ordnance Egg: 5%
Here is the fastest way to get the Founder Rooster:
- Obtain a Sergeant Hen: Get Scratch Eggs from Cosmo Brat, and hatch them until you get a Sergeant Hen. Use Sergeant Hens to farm Thunder Eggs. They have a 100% drop rate.
- Collect Royal Eggs: Place a Crest Rooster in your Coop to produce Royal Eggs.
- Get Baron Cluck: Open Royal Eggs until you hatch Baron Cluck (6% chance).
- Hatch Fortune Eggs: Place Baron Cluck in your Coop or the incubator to lay Fortune Eggs. Opening these gives you a 56% chance to hatch the Founder Rooster.
Once you have obtained the Founder Rooster, immediately place it in the incubator to start farming the Colossus Egg.
2. Chicken Boss Fight

You can earn Colossus Eggs by participating in the Chicken Boss Event. You must deal at least 1 million damage to the Chicken Boss to reach the second-to-last damage tier and receive a Colossus Egg. The Chicken Boss fight rewards another Colossus Egg at 5 million damage.
However, the Chicken Boss only appears a few times per hour, so I don't recommend this as the most reliable way to farm large quantities of Colossus Eggs. The Founder Rooster method is way better.
