Update 4 for Grow a Chicken Fighter is a systems patch more than a content drop. It adds seven new chickens and a Trophy Egg, but the bigger changes sit in the menus: an Arena Shop tied to Season 1 medals, milestone rewards attached to the Index, unlockable player titles, automatic Battle Charm crafting, and a bulk egg-opening button. There is also a volcano event running on the island.
Quick answer: Before spending anything, open the Arena menu and compare your Season 1 medal balance against the Trophy Egg’s 900-medal price, then open the Index to claim the milestone rewards you have already earned and check whether your flock space has increased.

Arena Shop prices and the Trophy Egg
The Arena Shop is the headline addition because it turns Season 1 medals into a real currency rather than a leaderboard number. It sits behind the ARENA button, under the SHOP tab, and the stock is a mix of cheap consumables and expensive eggs. The Trophy Egg is the second-most expensive item on the board, sitting below the Ascension Egg.
| Item | Arena Medals |
|---|---|
| Charm Dust x250 | 80 |
| 2x Corn (15M) | 110 |
| 2x Money (15M) | 125 |
| 2x Hatch Luck (15M) | 150 |
| 2x Damage (15M) | 200 |
| Fortune Egg x1 | 250 |
| Colossus Egg x1 | 650 |
| Trophy Egg | 900 |
| Ascension Egg x1 | 2000 |
Check Arena Honors before you buy. The two tracks draw on the same Arena progress, so a purchase made early can leave you short of a threshold reward you were close to reaching.
The 7 new chickens: don’t sell before testing
Seven chickens joined the roster with this patch. The practical warning is about bulk actions rather than stats: if you run bulk selling or bulk fusion the way you did before the update, you can dump a copy of a new chicken before you have ever seen what it lays or how it performs in the PIT. Inspect each new entry once, favorite the ones you want to keep, and only then run your usual cleanup.
Index Milestone Rewards and extra flock space
The Index used to be a collection log. Now it pays. Discovering chickens pushes you through milestone tiers that hand out money, Charm Dust, luck boosts and, most usefully, extra flock space. Open FLOCK and then INDEX to see where your current discovery count lands.
Because the milestones apply retroactively, established accounts often have several tiers already cleared. Confirm the flock space bonus specifically, since a larger coop changes how aggressively you can hatch before you need to sell.
Open Max, auto-crafting, and the daily dice
Open Max is the quality-of-life change you will feel immediately. Instead of tapping through single hatches, the Flock menu now offers a button that opens the maximum number of eggs the game will allow in one go, which matters most when you are burning through a stack of Ascension or Blazing Eggs.
Battle Charm Auto-Crafting is a toggle, not an upgrade, so it does nothing until you switch it on. Turn it on if charm farming is your current focus. Offline earnings were also improved, and a daily dice roll now sits alongside them, paying out a mixed bundle. A single 2-hour offline roll can return figures in the tens of millions of money and XP along with eggs and 500 Charm Dust, though the exact amounts scale with your account.
New game passes and bundles in the Shop
Two passes were added specifically for the charm economy: Charm Luck x2 and Charm Dust x2. Both aim at the same bottleneck, which is how slowly Charm Dust accumulates when you are rolling charms on a single chicken. The Shop also carries a separate Charm Dust tab where dust crates are sold directly.
| Pass or bundle | Robux |
|---|---|
| Elevator VIP | 54 |
| Speedy Sneakers | 54 |
| Big Coop | 72 |
| Double Money | 108 |
| Double Corn | 108 |
| Everything x2 | 198 |
| Auto Rebirth | 360 |
| Fusion Master | 432 |
| King of the Coop | 540 |
The volcano event: break the pressure vents
The volcano event is signposted with on-screen banners so you cannot miss the start. The sequence runs from “THE ISLAND IS SPLITTING OPEN!” to “A VOLCANO IS RISING FROM BELOW!” and then “THE VOLCANO HAS EMERGED!” Once the volcano is up, the pressure warning appears and Pressure Vents spawn around it.
Each vent carries a “CALL YOUR CHICKEN TO BREAK!” prompt. You do not attack the vents yourself. Send your chicken at them and clear as many as you can before the pressure meter tops out. If the timer beats you, the volcano erupts and covers the area in lava.
Player Titles and their unlock conditions
Titles live under their own TITLES menu, and each one lists the requirement that unlocks it. Several are tied to systems you are already using, so it is worth a look after you claim your milestones. The current set includes Hatch 1,000 Eggs, Hatch Goblin, Event Regular, Event Chaser, Event Aspect, Dust Burner, Lucky Cluck, Grandmaster, Arena Champion, Tower Climber and Ability Spammer.
Note: unlocking a title does not equip it. Open the menu and select one, or you will keep playing with an empty tag.
What to do in your first few minutes back
One more thing worth doing on the way in: the ticket icon opens the code redemption box, and CHICKENCLASH is circulating alongside the update. Type it exactly as written and press redeem to see what it pays out. Codes in this game tend to be short-lived, so if it returns an invalid message, it has already expired rather than been mistyped.
