What is the percentage that dragon eggs spawn in lootable chests?
I am asking this because for the past month I have looted at least 30 chests in my hardcore world (strongholds, mineshafts, spawners, fortresses, etc) and I have not found a single dragon egg.
I am not asking to increase the spawn percentage, obviously it has to be low because dragon eggs are super precious, but I just wanted to ask what is the percentage of them spawning?

Mod Version:

Curseforge version: 45.1.16

DefaultConfigs folder:

#Should Ender Dragon Eggs replenish on the exit portal after a respawned dragon is deafeated?
#Useful for multiplayer scenarios.
replenish_eggs = true
#Should dragon eggs generate in treasure chest loot tables?
#Useful for multiplayer scenarios and offering alternative ways to obtain eggs.
#Different types of egg breeds can be found in different chests (if configured.)
use_loot_tables = true
#Should Dragon Eggs adapt to their environments and change breeds?
update_habitats = true
#Number of times a dragon is able to breed.
#Range: > 0
breed_limit = 10
#Allow the vanilla ender egg to be interacted with? (Hatchable)
#Useful to help with mod compatability
allow_egg_override = true

Values are % chance for each roll on a loot table.
