AnimalWeights

Animals gain a hidden weight (0-8) based on how well they're kept. Weight scales the items and XP they drop when killed, so spacious, well-built farms out-produce crammed 1x1 cram boxes - and neglected animals get sick and stop breeding.

Based on the "Animal Weights" suggestion by u/Axoladdy on r/Minecraft: https://www.reddit.com/r/Minecraft/comments/1te0m69/

How weight works

Every few minutes each tracked animal is scored on four husbandry conditions:

Condition	Met when...
Light	light level >= 14 where it stands
Water	a water source is within a few blocks
Grazing	it stands on grass or moss
Stretching	no other mob is crammed into its space

The more conditions met, the higher the animal's target weight; its weight drifts toward that target over time. A crammed animal can't climb past weight 2, and one with no space, no light, and no water sinks to 0 - sick.

What weight does

More drops & XP. A maxed weight-8 cow drops roughly +7 beef, +7 leather, +7 XP over vanilla. Drops trend up naturally near water and around villages.
Sick animals (weight 0) can't breed and show a visible "unwell" cue.

Tracked animals

Cow, Mooshroom, Pig, Sheep, Chicken, Rabbit, and Goat - all configurable.

Commands & permissions

Command	Permission	Default
`/aw check` - weight + conditions of the animal you're looking at	`animalweights.check`	everyone
`/aw set <0-8>` - set an animal's weight	`animalweights.admin`	op
`/aw reload` - reload config	`animalweights.admin`	op
`/aw info` - plugin info	`animalweights.admin`	op

Configuration

Everything is tunable in config.yml (weight range, evaluation interval, each condition's threshold/radius, drop & XP scaling, the sick effect, tracked-mob list), then /aw reload.

Compatibility

Built for Paper/Spigot/Bukkit/Purpur 1.21.1+ (tested on 1.21.11, Java 21). Not Folia-safe.
