Fluker's Buffet Blend Adult Bearded Dragon Formula, 2.9 Ounc

When i feed my beardie this would i need to sprinkle some powder calcium or does it already have enough on it?

Are we supposed to soak these before giving them to our beardies? The red pellets are hard as a rock. I cant squish them between my fingers.

Should this have come sealed ?

Would this be fine for a juvinile bearded dragon ?
