Marcel,
I would really try to lizard scent that pinky before you force feed a chick leg part. Almost any skink will do, I think, but if you can get an anole, that's even better. if any of the pet stores have small lizards around you, you can go ask to look for shed skin in the tanks. Usually, they don't mind giving you all you want. Then you simply wet the pinky a small bit, and stick the shed to the pinky. That usually works wonders on bloodreds!
