When using Stockbook, sometimes the need arises to change a certain piece of information over an entire group of animals. To do this you should use the 'Bulk Changes' feature. This allows you to select a group of animals and change a piece of information for the entire group, without having to do each animal individually.
How do I delete observation codes, change dates and observation codes and herds?
NOTE: A bulk change cannot be 'Undone'. Please ensure you do a backup before doing any bulk changes.
