Sheep and cow question

Hi reddit,

I have been playing aoe2 for about a week now and something that always bothers me is sheep and cows. I have a really hard time finding them. Also, even when I "find" all of them, I i don't know if I found them all. I just want to know how many sheep/ cows spawn on the map at each base. And how do I find all of them.

(Hope this gets attention)
