If a herd is no longer active in the farm you can remove this from the map and seperate it from your active livestock figures while keeping the records stored.
Mobile
Open the Herd
Tap the three dots in the top right
Select archive
Web
Open the Herd
Tap 'More' in the top right
Select 'Archive'
Once a herd is archived its marker is hidden from the map and the herd will appear in a separate 'archived' section of the livestock list. The animals in that herd won't contribute to the active total for your farm.
If you want to unarchive a herd simply follow the steps above but instead of 'archive' the menu will say 'unarchive'.
Viewing the herd's details
You will still be able to view the herd on the herd list and see it's history. The moves this herd has been will still be part of the field history.
If you delete a herd then the herd history will be deleted and none of its movements will appear of your field history.
Herd splitting/merging is on the product roadmap so in the future there will be an easier way for you to mix animals between herds. If you would like more information or are keen to be a tester message support@fieldmargin.com.
