Hi everyone, it's my first post here!
I got my last Crappie going with very small worms. I can't remember where I got them, probably dug in the garden. Try to attach it to a thin monofilament line so you can tease him with it. Tie an overhand knot near the end of the line and then poke the line through the worm with the help of a needle. The knot will help it stay on the line until he bites it. Kinda like fishing!
Note though, I have never gotten ANY crappie to eat dead or prepared food! If you insist on prepared food, good luck, and definitely keep us informed how it goes. My favorite one, Slab, I kept for over four years and he was very friendly. My last one, Albert, was very friendly too, and he was named after the famous scientist cause he seemed so smart.
