For a curious bonus, as shepards produce food faster than farmers, how could that work?
Sheeps should cost some wood, and they can be generated in the town center. They should have a very fast creation time (to avoid interruption of villagers production as they come from the TC ) and they dont take population. Maybe they could create them from feudal or castle, even after researching an UT.
The advantage is that the food income should be higher, and you can also gather 6 villagers in one sheep, which saves space. Also, you could send produced sheep to an ally. Tatar will appreciate that. A pro lem is that they could be stolen too.
To balance them, the prize and production time should be discussed.
Opinions? Which civ had a huge tradition in shepards? Dutch?
