Chicks feed off each other's fear. Try taking a couple off by themselves for a short while as you handle them; when done put them back with the others and the take a couple different ones. By doing this you may find them less skittish. Hopefully they will become a less scared of you. I have four Japanese bantam chicks I am doing this with. Once in my hands they calm right down.
