I have no idea @RavynFallen I have only seen wet feather in my old ducks and after molt it's taken care of. Warm Compresses may help if the oil gland isn't working properly if it isn't genetic. Still maybe worth trying.I know that there are definitely ways to help keep her feathers oiled, I just can't remember what was best to use for it... but I seem to recall at least one duck that got injured in the tail area that damaged their oil gland, I believe...

Was it either of you that knows what can be substituted for a ducks natural oils?
