Slab hog great catch! As to the spawning ,you are right more so about the crappie you caught since they were mostly white crappie which will spawn as much as 3 weeks later than the Black Crappie. They like it a bit warmer water temp wise usually at 65 and above. I bet the 2 that Ditch said were turning were male Black Crappie!! I believe based on the development of the eggs that a few of the larger black crappie are already spawning on the upper end of the Big G .
