Animal Weights
No reviews yet
Husbandry mechanic for vanilla farm animals — cows, pigs, sheep, chickens, rabbits, and mooshrooms gain a 0–8 weight value that responds to how well they're kept and scales their drops and XP.

Animal Weights
A husbandry mechanic for vanilla farm animals. Every cow, pig, sheep, chicken, rabbit, and mooshroom carries an integer weight (0–8) that responds to how well they're kept — and that weight scales the meat, leather, and XP they drop when killed.
Suddenly your farm layout matters. Cramped pens of starving animals drop less. Roomy, well-lit, well-watered pastures with grass to graze produce fat, valuable animals.
Original concept: u/Axoladdy on Reddit.
How it works
Every in-game day at dawn, each target-species adult is evaluated against four living conditions in its surroundings:
| Condition | What satisfies it |
|---|---|
| Light | A block within 8 of the mob has brightness ≥ 14 (torch, lantern, full daylight). |
| Water | A water source or filled water cauldron (bucket-filled or rain-filled) is reachable from the mob — horizontally adjacent (or one block below) a cell it can walk to. Fences and walls block reachability. |
| Grazing | A grass or moss block is directly below a cell it can walk to. |
| Stretching | The mob has at least 6 walkable cells reachable around it (no fences or other farm animals blocking). |
The number of conditions met determines the daily weight change:
| Conditions met | Weight change |
|---|---|
| 4 | +1 (thriving) |
| 3 | 0 (plateau) |
| 2 | −1 (slipping) |
| 0–1 | −2 (suffering) |
Weight is clamped to [0, 8]. New mobs spawn at weight 1.
Drop scaling
When a target-species mob is killed, its primary drops and XP are scaled by its weight using an accelerating curve:
| Weight | Drop bonus |
|---|---|
| 1 | +0 (vanilla) |
| 2 | +1 |
| 3 | +2 |
| 4 | +3 |
| 5 | +4 |
| 6 | +6 |
| 7 | +8 |
| 8 | +11 (peak payoff) |
Primary drops by species:
- Cow / Mooshroom — beef (raw or cooked), leather
- Pig — porkchop (raw or cooked)
- Sheep — mutton (raw or cooked), any-colour wool
- Chicken — raw / cooked chicken, feathers
- Rabbit — raw / cooked rabbit, hide (rabbit's foot is not scaled — it stays rare)
Sick state (weight 0)
A mob whose weight falls to 0 is sick:
- Slowness I is applied continuously.
- Breeding is blocked — both parents' love state is reset if either is sick.
- Drops are penalised — each primary drop has a 50% chance of being removed entirely, and any stack that does drop is capped to a single item.
Babies
Baby animals are skipped from all of the above — no weight evaluation, no slowness, no drop scaling. Babies grow up in ~20 real minutes; the mechanic is meant for the long-term husbandry signal of an adult animal.
Compatibility
- Minecraft: 26.1.x
- Loader: NeoForge 26.1.x
- Required on: client and server (both sides need the mod installed)

Default state: weight 1, vanilla drops A freshly-spawned animal wandering the world starts at weight 1, vanilla drops, vanilla XP, no sickness. In open terrain wild animals usually plateau here -
Cramped pens make animals sick Stuff a herd into a tiny pen with no light, no water, and no grass and their weight ticks down every in-game day. At weight 0 they turn sick — Slowness I, no breeding, and their drops get capped and culled. -
Good conditions push weight up Give an animal light (≥ 14 brightness), water (a source block or filled cauldron it can reach), grass to graze on, and at least 6 walkable cells around it, and it gains weight every day at dawn. Three of four conditions plateaus it; all four push it to 8 -
Peak: weight 8 A well-kept pen converges on weight 8 and stays there. This is what "thriving" looks like. -
The payoff, drops scale with weight Kill a weight-8 cow and instead of 1–3 beef you get +11 extra primary drops on top of vanilla. The curve is accelerating, so weights 7 and 8 are where the real payoff is. -
The payoff, drops scale with weight You get a lot more drops -
Gameplay screenshot Note: There are no labels above the animals in the actual mod, this is what it would look like -
Every farm animal carries a weight Cows, pigs, sheep, chickens, rabbits, and mooshrooms all get an integer weight from 0 to 8, shown above their head. New mobs spawn at weight 1.
