"Who makes himself a sheep will be eaten by the wolves."
Baaaah-ad are the night without a wool blanket for warmth or mutton for the table! Though antiquity would portray the kindly shepherd as a simple image of piety, there is nothing easy about raising sheep. Through care, study, and the skill of Sheep Herding, the avid herdsman can take on a flock of his own!
Females give 1 wool per each 10 productivity, rounded down to multiples of 10. Males seem to only give 1 so not sure what productivity does for them.
