Well I know you could keep a barrel of milk near young animal pens if your breeding females couldn't stretch their milk, but now I have a pair of girl piglets that are taking starvation damage despite having a barrel of milk near their pens; the only thing is I did kill off all the adult sows (cleaning and re-organizing my animals to be more efficient since I don't play as much now). So do they need a nursing mother animal of their species alive to trigger young feeding, and only use barrel milk if the mother is depleted?
Or is this just a case of baby pigs not drinking from barrels?
