This is an old thread, but I would always recommend leaving chicks with a broody hen over taking care of them. All you have to do is watch it once, and those chicks within a week are already integrated into a flock. They know how to find food and forage, they know who to stay away from, and it is so much easier and healthy. Yes, you trade off getting to handle them and having them let you cuddle them, but when they grow up and start laying, they usually are just as friendly.
