Minecraft 25w06a Update - What's New
Warm and cold chickens arrived with their own blue and brown eggs, deserts and badlands got short and tall dry grass and cactus flowers, and random ticks began to reach every loaded chunk in simulation distance.
Overview
Minecraft 25w06a is a weekly development snapshot for Minecraft: Java Edition, published on February 5, 2025. Snapshots are Mojang's weekly previews of in-progress features (development week 6 of 2025), shipped early so the community can test and report problems before anything is finalized. This one logs 8 changes you can try in a throwaway test world.
The work in this update spans new features, changes, and technical. On the new features side it brings Warm and cold chicken variants, with blue eggs for cold chickens and brown eggs for warm ones and Short and tall dry grass in deserts and badlands.
This build is part of the development cycle leading to 1.21.5 (the Spring to Life drop). Treat it as a preview rather than a destination: features can change, be renamed, or be cut entirely before they reach the stable release, so it is meant for testing and feedback, not for your main world or a live server.

What This Means
For players
Snapshots are opt-in through the official launcher. Always make a copy of any world before opening it in 25w06a, because development builds can corrupt saves and there is no guarantee the world will open in a later version. Use a fresh test world to try the new content safely.
For server admins
Do not run 25w06a on a public server. Snapshots are unsupported by server software and most plugins. Spin up a private staging instance, confirm your plugins load, and report regressions while there is still time to fix them before release.
Background & Context
- Snapshots ship roughly once a week during active development and are enabled through the "Latest snapshot" toggle in the official launcher.
- The content here was being developed toward 1.21.5 (the Spring to Life drop); individual features may have been adjusted, renamed, or removed before that version shipped.
- Always keep a backup of important worlds before changing versions; the Astroworld versions database tracks client and server compatibility for 25w06a.
