This mod adds ducks to the game.
You can find Mallard ducks in the swamp and Pekin ducks in the taiga biome.
You can bred them with seagrass.

Also, they'll lay eggs (can be boiled and eaten) just like chickens and will be eaten by foxes.
These eggs are dyeable, because why not?

They will drop Duck meat (you can cook it) and have a Donald Duck skin when you rename them to Donald or Donald Duck.

Other available custom skins:
- Scrooge McDuck
- Darkwing Duck
- Ducktor

- Daffy Duck
- Dewey (blue)
- Louie (green)
- Huey (red)

You can find a Common Config for the spawnrate in your config folder.

If you want a mob to spawn in another mods biome.
You have to change the biome_name line:
For example to:
biome_name_... = "biomesoplenty:bayou"

For fabric you only need to write the biome name: bayou

To let it spawn in more biomes you have to put a comma (,) between the biome names like this:
biome_name_... = "biomesoplenty:bayou,minecraft:swamp"

Don't put spaces between them.

In the (forge) 1.19 version the spawn settings config was removed and can be changed with the biome tag 
and biome modifier json files.

The fabric versions didn't change in 1.19
