This is a short guide explaining the different options in the mod's config:

Whether the game should use the mod's updated chicken model

Note: Some birds do not have songs, so they do not have a song distance field.

How far away the bird's calls can be heard from (in chunks). Calls usually diminish much closer than songs.

How far away the bird's songs can be heard from (in chunks). Songs can typically be heard from further away compared to calls.

How often the bird will spawn. A higher number will result in more spawns. (not a percentage!)

Note: Set the spawn weight to 0 to stop the bird from spawning.

The minimum number of the bird that will spawn at a time

The maximum number of the bird that will spawn at a time

Warning: Min group size must be equal to or smaller than max group size! Otherwise, the game will crash 😱

Note: The number of birds that spawn at a time is between the min group size and the max group size (inclusive)
