That's interesting Pat. I have a mud bottom and lots of FA. I have created gravel beds and some structure piles to help with my fry survivability, but don't get to observe most of my fish beds. Is your pond fairly clear? I have read that BCP spawn first (at least before BG and LMB) but never considered the predation the existing BG are doing to the crappie fry. Can you boost their cover?
