Vanilla Backport X Incubation Compat

Features

Blue and brown egg nests now generate throughout the world!

I added some biome tags for compatibility with other mods.

Added twig blue nests in:

• Taiga
• Snowy Taiga
• Old Growth type biomes
• Windswept type biomes

blue egg nest in a field biome (Biomes O' Plenty)

Added twig brown nests in:

• Savanna type biomes
• Jungle type biomes

Minimal change to the chicken_nest tag, nests with regular eggs no longer generate in taiga biomes

The textures of the brown and blue eggs in nests have been changed, each now has a unique texture and improved visual appearance
