When a Farm management program is used, the group / pen updates automatically when an animal moves to another group / pen. No further action is needed.
When you have a stand alone system without a Farm management program, the group / pen can be changed manually or automatically:
Manually. Select the correct group / pen on the animal page when an animal moves to another group / pen, or change the group / pen for multiple animals at the same time via the Quick Entry.
Automatically. Use the production based housing (Settings > Calendar > Production based housing) to automatically move animals to a different group / pen when the production state of the animal changes.
