The provisioners on Albion all sell goat cookies or crackers or something like that. You have to have them in your inventory to extract what you are looking for. Then you will get a pop up to distract the goat with the item, while you do the deed.
to get the evil goat trophy you need to refuse a goat in a group of 5, it will give you a different pop up saying the goat looks more aggressive than the others.
