Mr. Toad, who was originally used for scenting mice to try to get Addy to eat mice, retired from scenting, but by then I was (of course) really attached to him. I put him in with the torts, and he's lived there for about six or seven months. They run on opposite schedules. When they are out during the day, he usually sits on top of one or the other of their hides. He even basks under their heat lamp. When it gets dark, the torts are asleep and Mr. Toad comes out and sits in their tiny creme brulee water dish for a lot of the night. I feed him in a feeding container, because the torts viv doesn't have a lid.
The torts are too big for crows, and I don't have any resident hawks, plus they'll be under cover most of the day.
