Simple Incubator
by InterPlay02
Simple Incubator, a NeoForge mod for 1.21.1, adds a single machine that hatches the eggs of creatures, including vanilla spawn eggs, and exposes its behavior through a config file and a datapack.
What it does
The mod's central block is an incubator machine. Players place an egg in it and the machine hatches the egg after a set wait, which replaces the normal spawn egg behavior for the eggs it accepts. The wait time is adjustable in the config file, so a server can make hatching faster or slower to suit its pace.
Mobs can be set to drop spawn eggs on death, and the chance of that drop is configurable. Dropping spawn eggs can be turned off altogether, and mob spawner drops can be made to break the spawner instead. A datapack can define the default list of eggs the incubator accepts, so adding more eggs from other content is done without changing code.
The mod runs on NeoForge only, for 1.21.1, and it needs to be installed on both the client and the server. It reads energy in the Forge Energy (FE) system, so it can take power from other energy mods. The author plans a way to adjust the attributes of creatures hatched from altered eggs, but this is not yet part of the release. The source code and issue tracker are public.
Key features
Single incubator machine
One machine hatches the eggs of creatures, so the mod adds a single new block rather than a set of machines.
Configurable egg drops
Spawn egg drops from mobs can be enabled or disabled, and their drop rate on death is set in the config file.
Adjustable hatch time
The time an egg waits in the incubator before hatching can be changed in the config file.
Spawner drop handling
Mob spawner drops can be set to break the spawner, which affects how spawners are collected.
Datapack egg list
A datapack defines the default list of eggs the incubator accepts, so more eggs can be added by datapack.

Who it’s for: Players and server owners who want a simple machine for hatching spawn eggs on NeoForge 1.21.1, and who are willing to edit the config file or write a datapack.
