Make sure that your feeder and waterer is chick friendly. You might want to put some rocks in the waterer lip if it is deep to prevent drowning. She will drop some feed for the chick but it is best if the chick can reach the feed, too. You can put a little feeder near the nest box if necessary but the other chickens might take it.
What I like to do is use bricks as steps up to the feeder/waterer for the chicks (and concrete blocks next to the bricks), but be very careful of drowning potential.
