Yes, you really need to research the different ducks and geese - their preferred diets will vary all over the place so you have to target exactly what you expect them to be eating. As for coquis, I'm sure there are varieties that will munch down on them, but again must research to find out which ones. I've used mallards on the mainland to absolutely clean a property of snails and slugs, so I'd bet there's a coqui-muncher available.
