Whether or not changing the food helps the poo, I assure you changing it is the right thing to do for the chicks. Otherwise I would suggest not having them, And I don't mean that to be ugly. But to let you know how sincere I am about the health of your chick and hence your future flock as well as you current one.
She sure is a pretty girl!
Were you able to find the poop chart? I think this is the link. Hope it helps.
