Strange mix of honey/pollen in brood: cause for concern?

[chrissv]

I'm a new beekeper; I hived a package on 4/13 with new undrawn foundation in the frames. Last week's inspection showed a nice frame of capped brood (consistent with the bees to be born a few days later): http://tinyurl.com/r9zgag

This week's inspection showed that same frame to have the center cells empty, consistend with newly born bees: http://tinyurl.com/oj4s3z

But it looks like the bees are putting pollen and nectar in those newly vacated cells (I also see some eggs).

Should this cause me some concern? In that super there are about 2 1/2 frames of undrawn foundation, so they don't have to put the honey there...

Thanks! - Steven

No, they don't need to put the honey there. Actually, they do know where they need to put their pollen, nectar/honey, and brood. You can trust them.

Mr Clemens answer is both correct and adequate, But let me add some "whys". First year colonies in the establishment mode grow down from the top. In parallel with brood rearing, they must accumulate reserve stores. Growing down, the starter builds the reserves at the top. Pollen is difficult to move and would impede downward growth. What you are seeing here is the transition from brood to reserve accumulation.
