CluckNet

by hijimasa

CluckNet is a Forge transportation mod that sends network packets by having chickens carry them between blocks, following RFC 1149 IP over Avian Carriers.

What it does

Two blocks, a Packet Sender and a Packet Receiver, are placed with a walkable route between them, and a message is written into the sender's interface using a book, quill or sign. Chickens then walk across the world carrying chunks of the message, and the receiver reassembles the text once enough chunks arrive. Chat often shows the message before the chickens have finished walking in.

The design is lossy by intent. Chickens cannot fly, so they can stall on steep ledges, drown in water or die to wolves, and a chicken that dies leaves a paper item with a preview of the lost chunk. When too many chunks go missing, the receiver sends a negative acknowledgement, and the sender retransmits the missing pieces.

CluckNet runs on client and server, so the server and every player need it. It is published for Forge only, for Minecraft 1.20.6, with 0.1.0 as the latest file released on 2026-05-20. The code is open source under the MIT License, and the source code and issue tracker are public.

Key features

  1. Chicken-carried packets

    Chunks of a message travel physically between a sender and a receiver block, carried by chickens walking across the world.

  2. Retransmission on loss

    Missing chunks trigger a negative acknowledgement, and the sender resends only the pieces the receiver lacks.

  3. Lossy by design

    Obstacles, water, mobs and player attacks all cause dropped packets, so delivery is only attempted and throughput is capped.

  4. Receiver reassembly

    A receiver rebuilds the written message from arriving chunks and hands back a written book once reassembly succeeds.

Use cases

Network teaching sandbox

Players can watch how loss, latency and retransmission affect a message, using the chickens as a visible model of the packet path.

Roleplay and comedy builds

The chicken courier is suited to servers that want an absurd, playful take on networking inside the world.

Who it’s for: Players who enjoy novelty mechanics, and server owners who want a joke network for a sandbox or a teaching world. Builders with a route of walkable ground between two points will get the most out of the sender and receiver setup.

Questions

Does CluckNet need to be installed on both sides?

Yes. Installation covers the server and each player's game.

Which loader does CluckNet support?

CluckNet is published for Forge only, for Minecraft 1.20.6, with no files for other loaders listed.

Why do messages arrive incomplete?

Chickens can drop packets by dying, drowning or getting stuck, so the receiver may need a retransmission before the message is complete.

What the author says

An implementation of RFC 1149 "A Standard for the Transmission of IP Datagrams on Avian Carriers" for Minecraft. Packets are physically carried between blocks by chickens. Their natural inability to fly, navigate obstacles, or survive mob attacks reproduces real IP-style packet loss and latency — obstacles, water…
