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.
