Someday you will turn in to a crappie fisherman exclusively if you keep catching them that big. Those are huge for Bluegrass Crappie. I'd love to hook into a few of those that size.
Were they shallow or deep? Near a ledge perhaps? I caught one that was about 12" long at Otter a week or so ago.
How long were those big crappie? Did you measure their lenght? Were they full of eggs? And were the eggs ripe yet?
Sounds like you have a good time out there.
