Yup, keep handling them. My six incubator-hatched chicks are about a month old now and going through a serious phase of the sillies: they have too much energy, and they're at that age when their mother would be starting to lose interest in them, so they're hyper-alert and bouncing off the walls. Currently they spend the day outside, and I bring them in at night. Catching them in the morning is easy; catching them in the evening, when they're over-stimulated from being outside, is a real nuisance. However, I have noticed that they are getting used to being held. They still scream and fuss when I'm trying to catch them, but once in the hand they settle down and say, "Hi! When's that really good food we get when we come inside?"
Another good trick is to take an old chair out to the coop and spend some time every day sitting with them. The more time you spend in their presence, the calmer they will get about you. They start seeing you as part of the flock, and if you happen to be a flock member who brings them treats, you will be VERY popular!
Chopped hard-boiled egg is a favorite treat with these kids. It's very high in protein, so you don't want to give them too much, but they crave the protein big time. Getting chicks to taste something new and different can be hard; I generally tap it with my finger, and they get very curious.
