Translation:We are looking for big pigs, big sheep, and big horses.
No, it's accusative plural, same as nominative plural. Accusative singular would be velkou ovci
Well, my answer here was "We are looking for big pigs, big sheeps and big horses" (sheeps as ovce is plural accusative) and marked me wrong. Why is singular "sheep" if "ovce" is used and not "ovci" (as I guess it should be)
