Those are all last years hatch, not that it matters but they could pose an issue. Fillet them and see if they contain any eggs, if they are female you'll see the eggs if sexually mature but this is spawning time in your area so if they are mature it may be too late. How big are your F1's and HSB right now?
Get all your buddies lined up and chuck jigs and pull every one you can get caught-out... at this point that's all you can do. It's all hands on deck, you can make a difference if you put in the time. Another crappie catch technique is set Z traps or cloverleaf traps with glow sticks in the center (at night) and float the traps with noodles as close to the surface as you can.
