Never, ever give Bear turkey by hand again
A trick that might have worked: cover his nostrils with your finger. He should lessen up biting to get air into his mouth to breathe. My aunt told me to do this when bit by a bird.
You didn't mean to hurt Bear. Animal instinct kicked in when you was trying to get him off your finger. When something hurts like hell you tend to react quickly and sometimes violently.
One question: do ferrets carry any disease/bacteria that he could have passed on to you? Something that wouldn't hurt him but is not normal to humans?
