Herbs and spices for ducks

[AimToMisbehave]

Does anyone know about herbs/spices for ducks? I saw something online somewhere that recommended small amounts of oregano or garlic or turmeric as supplements and to address various ailments, and I wondering if those were true, and if there were other herbs I can grow at home for them? I looked through the Ultimate duck food and treats thread, but couldn't find anything about herbs/spices...

Maybe try looking for herbs, spices, plants, etc that are toxic to birds first.
