I caught Frank this afternoon, and his foot looked fine. Plus, he bit me in two different places, and raised quite a welt. No attempt at pictures, you'll have to take my word for it that he was feisty and ready to go. So, after smearing his foot one last time with medication, I put him back into the Finsterium. He and Sally spent the rest of the evening together, although at the moment Frank is sleeping on top of a nest box, and Sally is standing on one foot on the perch. Maybe I'll have to catch her and check out her toes.
