From Vintage Story Wiki
Sheep eat animal feed placed in a large trough . Troughs hold portions of dry grass or grains and sheep will consume either grass or grain. When the Block info HUD says ewes are ready to mate, they need to eat 10 portions of food from a large trough. After a pregnancy time of 20 days, ewes bear one lamb at a time, chances for male or female are 50/50. Lambs take 336 hours to grow up, and the ewes will need 4-11 days break before they are ready to breed again.
Note that male sheep (and sometimes the females) always attack players when in close range, but they will stop doing so after 10 generations of breeding.
