How to Get the Shockwave Hen
The Shockwave Hen is a Epic chicken from the Colossus Egg, published at 28%. That works out to about 4 hatches before you should expect one. The Colossus Egg has exactly five outcomes and its published percentages add up to 100%, so unlike several other eggs in this game there is no missing slice to account for. Below: the full table with expected hatches worked out for every row, where the Shockwave Hen sits among those five, and one route into this egg that is being reported but is not yet confirmed.
Where the Shockwave Hen sits in this egg
Of the five outcomes, 1 are more common than the Shockwave Hen and 3 are rarer. At 28% you should expect roughly 4 hatches, against 3 for the Rumble Rooster at the top of the table and 100 for the Storm Colossus at the bottom. Those figures are simple reciprocals of the published rates, not survey results: they tell you the average, and a single unlucky run can and will run well past them.
The percentages add up, which is not always true here
The five published rates sum to 100%. That matters because several other eggs in this game do not: the Arena Egg table sums to 102% and the Charm, Circuit and Fang Egg tables each sum to 101%. A table that overshoots means at least one figure is rounded or stale, and any expected-hatch number derived from it inherits that error. For the Colossus Egg you can take the arithmetic at face value.
One reported route we are not putting in the table
Community coverage of Update #3 reports a Colossus Egg to Catalyst Hen handoff that opens a Trick Egg chain. We are deliberately keeping that out of the table above. The five rows here are indexed drop data; the Catalyst Hen route is described by its own sources as reported and not yet confirmed in the live game. Mixing the two would make an unconfirmed claim look exactly as solid as a measured one. If it is confirmed, the table gets a sixth row and the percentages get rechecked — because five rows already account for 100%.
Step-by-Step
- Get hold of a Colossus Egg — it is the only published route to this chicken.
- Hatch it and budget around 4 hatches at the published 28%.
- Expect to see Ironcluck and Talon Titan and Storm Colossus even less often; everything above 28% will show up first.

FAQ
How do you get the Shockwave Hen in Grow a Chicken Fighter?
Hatch the Colossus Egg. It is the only published source, and it drops the Shockwave Hen at 28%, which works out to roughly 4 hatches before you should expect one.
How many Colossus Eggs does a Shockwave Hen take?
About 4 on average, from the published 28%. That is an average and not a ceiling: roughly a third of players doing this will still be empty-handed after 4 attempts.
Is the Shockwave Hen the rarest thing in the Colossus Egg?
No. Ironcluck (15%) and Talon Titan (10%) and Storm Colossus (1%) are rarer.
Do these percentages come from the developer?
No. They come from a community-maintained drop index, not from an official announcement. The five figures do sum to 100%, which is a good sign, but rates can change with any update — check the live game before committing a long grind.
