What would you do if you owned the cage?

A man and a woman rented a cage on your property. The man works and takes care of his family remarkably. The man suddenly dies outside the cage. The woman refuses to leave and attacks everyone who tries to enter. She has 3 children ages 2, 4 and 7. The state says you must provide for the children if you do not you will be locked up. They will not remove the woman. If you leave the cage open the children will probably wander out. You would still be responsible for them but if all of them come out you are not responsible for the grown woman. Once she dies the state will take the kids. How would you handle it.
