So, I wrangled up three cattle with the help of a friend. We got them penned away in little 2x5 boxes, a bull and cow in one, and a pregnant cow in another. The pregnant one had a food trough, which was filled with crap food and depleted within a day (like two days ago), so we planted more grass in their pens. Today, I look and the pregnant cow is dead. I check the other livestock, and the other cow is hungry, as well as a sow. The thing is, the living cow and the sow, are both held with a bull and, um, whatever you call a male pig.
So, is grass not enough to keep a pregnant animal alive? Do I need to expand the grazing area for them?
