Roost Ultimate - Terralith [ADDON]
by Tarantel
Roost Ultimate - Terralith is a NeoForge addon that adds Roost chicken spawning to the Terralith biomes for Minecraft 1.21.1.
What it does
The addon requires Geckolib, Roost Ultimate and Terralith. It works on client and server, so both the server and every player need it. Files are published for NeoForge only, for 1.21.1, with 1.0.0 as the single file released on 2025-11-30 and All rights reserved, which means it is not open source.
Roost Ultimate expands the chicken with more breeds and a breeding resource system. An advanced incubator called the Breeder creates new chicken variants and gives each one its own outputs, such as feathers, iron or gold. Chickens placed in a Roost produce higher-quality materials, including gemstones and magical items, which can be used to craft stronger tools and armor. This addon extends that system by letting the chickens spawn in the Terralith biomes.
Key features
Terralith biome spawning
Roost chickens spawn in the biomes added by Terralith, so the expanded worlds gain their own chicken populations.
Breeder incubator
The Breeder is used to breed different chicken variants and to create new breeds, with some experimentation needed to reach the desired traits.
Variant resource outputs
Each chicken variant yields its own resources, such as feathers, iron or gold, rather than only the usual eggs and feathers.
Roost production
Chickens placed in a Roost generate higher-quality materials, including gemstones and magical items.
