What hand raise mix are you using?
Is the temp warm enough, or not too hot?
I found mine took a couple of days to get used to the taste of the new formula and prefered it warmer than some other birds, but not too hot obviously.
You could try mixing a tiny amount of pureed fruit or veg or baby food in a jar into it, see if that entices them to eat. I added a small amount of mash pumpkin or carrot, not too much though as you don't want to take away the amout of baby food they are eating or make the taste too strong for them.
If you don't think they are getting enough food, try adding an extra feed so they are not missing out on their tucker.
Are you weighing them every morning before their first feed to see if they are gaining and not loosing weight?
I weigh mine every morning, gives a good indication if they are eating enough or if any problems arise due to stress sickness etc.
Let us know how things go.
