Mine do the same thing. Mama is sweet and will come right up and take food out of my fingers, but the babies are still wary. They "yell" whenever we try to pick one up. They're 7 weeks old this week (not really babies anymore!) and they're still jumpy with people. I just keep giving them treats and having the big hens take food out of my fingers. They'll figure it out. It's worked with my now big hens. Don't worry. They don't hate you!
