Female crappie "may" have eggs in them at any time of the year ... size of sac determined by time of year/location.
The progression goes something like this :
Spring Spawn - egg sacs at full size/eggs mature, dropped in multiple beds
Post Spawn - egg sacs mostly empty, but some may have leftovers
Summer - leftover eggs absorbed, new egg sac develops
Fall - egg sac grows larger, as more eggs are produced & grow larger
Winter - eggs develop, but at a slowed rate
Early Spring Prespawn - eggs develop at faster rate, with warming temps
Prespawn - eggs near maturity, fish begin migration to beds
So, as you can see, there is the possibility of a female Crappie having eggs at most any time during the year. Water temps & available foodsources determine how fast they develop.
