Post a pic. I doubt the frogs leg is broken though. Did it land on tile or carpet? I would be more worried about internal damage to the body or a cracked jaw.

Sometimes they prefer to eat in their den. In the wild and in captivity they sit with their face poking out so they can sneak attack. I have a large female hat doesnt get out of her den pretty much ever. She just sits there with her face sticking out.
