How to Get Catalyst Hen in Grow a Chicken Fighter Roblox Guide
Catalyst Hen is one of the rarest chickens you can hatch in Grow a Chicken Fighter Roblox. This chicken comes from the Colossus Egg and has a Secret rarity, with a hatch chance below 1%. Because of that, getting Catalyst Hen requires both a good supply of Colossus Eggs and plenty of luck.
The good news is that there is a clear progression path you can follow to increase your chances of reaching the Colossus Egg stage. Here is everything you need to know about getting Catalyst Hen, including the required chickens, hatch rates, stats, and how to get its stronger Inverted version.
How to Get Catalyst Hen
Catalyst Hen can only be obtained from the Colossus Egg. The chicken has a Secret rarity and its hatch chance is below 1%, making it much harder to obtain than most other chickens from the same egg.
The Colossus Egg can also hatch several other chickens, including:
- Catalyst Hen — Below 1%
- Storm Colossus — 1%
- Talon Titan — 10%
- Iron Cluck — 43%
- Rumble Rooster — 46%
Since Catalyst Hen has such a low chance, you should focus on building a reliable way to collect Colossus Eggs instead of simply opening eggs whenever you get one.
How to Get Colossus Eggs

The first major requirement for your Colossus Egg progression is Founder Rooster. This Legendary chicken comes from the Thunder Egg and has only a 3% hatch chance.
Because the chance is quite low, you may need to open a large number of Thunder Eggs before getting Founder Rooster. Setting up a way to generate Thunder Eggs regularly can make this process much easier.
A good option is Static Chick, which can be placed in your coop to help generate Thunder Eggs.
Static Chick has a 100% chance to hatch a Thunder Egg whenever it produces an egg. This makes it especially useful when you are trying to farm Thunder Eggs for Founder Rooster.
How to Get Static Chick
Getting Static Chick can also be part of your progression toward Catalyst Hen. One useful route is to start with Viking Rooster.
Viking Rooster has a 70% chance to produce Thunder Eggs, while Static Chick itself has a 14% hatch chance and is classified as Common.
The progression can look like this:
- Collect Nest Eggs.
- Try to hatch Viking Rooster.
- Viking Rooster has a 2% chance to come from Nest Eggs.
- Use Viking Rooster to help produce Thunder Eggs.
- Continue opening Thunder Eggs until you obtain Founder Rooster.
- Use Founder Rooster to progress toward Colossus Eggs.
- Farm Colossus Eggs and hunt for Catalyst Hen.
Nest Eggs are relatively easy to collect, making them a useful starting point for this progression.
Catalyst Hen Stats
Catalyst Hen is already a very strong chicken even without a mutation. Its starting stats make it a valuable addition to a late-game team.
A normal Catalyst Hen starts with:
- HP: 362
- Attack: 35
- Speed: 15%
- Power: 15%
These numbers put Catalyst Hen among the stronger chickens currently available in the game.
Its stats are also higher than some other powerful chickens, including Kraken Chicken and Storm Colossus. However, Eclipse Hen still has slightly better overall base stats.
Inverted Catalyst Hen Stats
If you are lucky enough to obtain an Inverted Catalyst Hen, its starting stats will be noticeably higher.
The Inverted version has:
- HP: 416
- Attack: 40
- Speed: 21%
- Power: 21%
The Inverted mutation gives the chicken around 15% more HP and Attack, along with an additional 5% Speed and Power compared to the normal version.
This makes an Inverted Catalyst Hen an even stronger option for players who are looking to build one of the best chickens available.
How to Get Inverted Catalyst Hen
There are two ways to potentially get an Inverted chicken. The first is simply hatching one directly from an egg.
Every egg has a 0.5% chance to produce an Inverted chicken. Since the chance is extremely low, getting an Inverted Catalyst Hen directly from a Colossus Egg is going to require a lot of luck.
The other method involves using the fusion system.
When fusing chickens, the chance of getting an Inverted result depends on the tier difference between the chickens. If the main chicken and the chicken being fused are the same tier, there is a 50% chance for the main chicken to become Inverted.
The chance becomes lower when there is a larger tier difference:
- Same tier — 50% chance
- 1-tier difference — Lower chance
- 2-tier difference — Lower again
- 3+ tier difference — Even lower chance
Because of this, having another suitable chicken for fusion can give you an additional opportunity to obtain the Inverted mutation.
Is Catalyst Hen Worth Getting?
Yes, Catalyst Hen is one of the strongest chickens you can currently target in Grow a Chicken Fighter. Its base stats are already higher than several other powerful chickens, while its Secret rarity makes it a valuable addition to an advanced lineup.
The main problem is not the chicken itself but getting enough Colossus Eggs to have a realistic chance of hatching it. With a sub-1% hatch rate, you should expect the process to take time. If you manage to get an Inverted Catalyst Hen, however, the result is even more impressive. The improved HP, Attack, Speed, and Power make it an excellent chicken to build around.
Getting Catalyst Hen in Grow a Chicken Fighter is a long-term grind because the chicken is locked behind the Colossus Egg and has a hatch chance below 1%. The best approach is to build your egg production step by step, starting with Nest Eggs and eventually working toward Founder Rooster and Colossus Eggs.
A normal Catalyst Hen already has excellent starting stats, while an Inverted version can become even stronger. If you are aiming for one of the top chickens for your lineup, Catalyst Hen is certainly worth farming for. The process may take plenty of eggs, but building a reliable egg supply will give you more chances to finally get the hatch you’re looking for.
