What Update #1 changed, in practice
- Incubator — a second hatching slot you buy for 300,000 cash (reportedly rebirth 3+). One chicken sits inside and lays continuously; egg storage and a luck boost grow over time. See the incubator guide.
- Inverted chickens — a 0.5% chance on any hatch for a stat-boosted variant; transfers through fusion at a reduced rate after HOTFIX 1.1. See inverted chickens.
- Chicken Boss event — an armored boss in its own arena; damage milestones pay Fortune Eggs and Colossal Eggs. See the events guide.
- Colossal Egg — laid only by Founder Rooster (about 25%) and earned from the boss; hatches Storm Colossus at about 1%. See the Colossal Egg page.

How we keep this page current
We log a row when a Roblox build timestamp changes, when an official event starts, or when a code goes live or expires. Patch contents are taken from the developer’s notes and in-game confirmation, not from speculation — so the Aug 22–29 row stays blank on contents until the update is actually out.
Last checked: August 22, 2026 — we revise this page after each game update.
Thanks for the feedback!
