Then the cluster grows and it is possible to lay wider area.
Then they are situation that center has capped brood and periphery has you larvae and eggs.
3 weeks later first capped brood has emerged and they are laid and reared to capped brood.

eggs and larvae (open cells)
That is very normal
larvae +eggs are 8 days and pupae are 13 days. = almost 1+2 weeks
