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.
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.
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:
A mob whose weight falls to 0 is sick:
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.
