Yes, if you reward equally on everything, the creature will pass everything as 'same' from what YOU teach it, allowing it's AI / Mind to make up it's own choice, by seeing how much the town rewarded him for such an action. Or if he is rewarded at all.
However, ensure balance! - Do not reward your creature again - as he will see this as 'getting attention' - and will water the fields more.
Just because you reward equally in %, does not mean you do so in count - this is also suggested! ^^
