How do I enter fostered piglets in PigVision?

You can enter them either in the transferred piglets column in either the farrowed or weaned screen (using the minus sign for fostered off and just a positive number for fostered on) or they can be entered via the Sows/Boars menu and piglet transfer. You can then enter the animal ID, date and how many went on or came off. You can also choose the source or destination sow by choosing the From/To sow column in the column setup.
