This mod makes it easier to breed horses with the best stats (or the worst). This is done by overwriting the method used to determine horse stats when breeding. The new method has 3 changes:

Chance to pass on maximum stats: In vanilla, when the code generated a number high than the maximum, it would give you a stat that much lower than the maximum. Now it give the actual maximum. The same applies to the minimum.
Keep matching stats: If you breed to horses with a near-identical value in a stat, it will pass it on without randomizing. This can be disabled in the config if you don't like it.
Configurable stat ranges: You can change the maximum and minimum stats in the config file to buff or nerf possible breed outcomes. This does not affect the values on naturally spawned horses.

This mod also overwrites the method used to determine horse fall damage. This is to give more protection to horses that can jump higher than the vanilla maximum. If you don't enable such horses, you won't see any difference.

For realism, horses can now eat baby chickens. This is configurable.

Llama strength from breeding now favors being closer to the parents' values. The chance of getting a llama stronger that the parents is now a flat 4% that doubles if both parents have the same strength instead of vanilla's 3% / input strenght. This value can be changed in the config.

Because this mod overwrites multiple vanilla methods, it may not be compatible with other mods that alter the same methods.
