The gate to the Trick Egg route
Catalyst Hen is a Secret chicken that hatches from the Colossus Egg at under 1%. It is currently the only known starting source of Trick Eggs.
Once obtained, keep it in the Coop or Incubator: every 10 minutes it lays an egg with a 98% Colossus / 2% Trick Egg split. After your first Trick Egg, switch to Trick Egg chickens like Domino Chick (about 10% lay rate) for faster farming.
Frequently asked questions
How do I get the Catalyst Hen?
Hatch Colossus Eggs until it lands - under a 1% chance per egg, so stockpile Colossus Eggs before a hatching session.
Should I ever recycle the Catalyst Hen?
No - it is the only known starting source of Trick Eggs. Favorite it as soon as you pull it.
