BredExempt
Your breeding and egg farms are quietly starving your natural spawns. BredExempt stops that.
In vanilla Minecraft, every animal you breed — and every chick you hatch from a thrown egg — counts toward the passive mob cap. Pack a pen with cows, sheep, pigs, or chickens and you push the loaded area toward its cap: fewer animals spawn in the wild around you, and your farm slowly chokes natural spawning.
What it does
- When two animals breed, it marks the newborn and both parents as persistent.
- When a chick hatches from a thrown egg, it marks the chick as persistent too.
Persistent mobs are skipped by the natural-spawn cap count — so your breeding and egg farms stop consuming the passive-creature cap, leaving that room for naturally spawning wildlife.
Commands & config
/bredexempt inspect— look at an animal: marked or not, why, and whether it still counts toward the cap. Click the output to copy it./bredexempt cap— live cap accounting for your dimension: counted vs cap, exempt vs wild.- Optional
config/bredexempt.properties— toggles for offspring / parents / egg-hatched chicks, plus an entity allowlist/denylist. Zero config needed by default. - Modpacks can use the
#bredexempt:allowed/#bredexempt:deniedentity tags instead — a plain datapack, no config edits.
Modded animals
Modded animals are marked exactly like vanilla ones when their mod uses Minecraft's standard Animal breeding flow — many vanilla-style farm/wildlife mods do. Modded wildlife gains spawn room when it spawns through the vanilla natural-spawning system in the standard creature category.
Mods with custom breeding systems, custom spawners, custom mob caps, or custom egg/hatching mechanics may not be covered — if you find one, open an issue and dedicated support can be looked at.
Server support
Relies on vanilla's persistent-mob cap exemption.
