Editing birth and weaning weights is easily accomplished via the Animal Data screen
Filtering Herd Page
You can filter the Herd page by tapping the header above the "Add" and "Remove" animal buttons. If you wish to edit a date for a calf it will be easier to find if you have "Calves Only" selected as the filter option.
Click on the white calendar icon next to "Birth Date" or "Weaning Date". Enter the appropriate monoth, day, and year, and press "Save" when complete. Note: Other data types such as weights and additional notes can also be edited using this method.
