1 a day isn't worrysome to me. Are there any signs of marks on the fish (like getting stabbed by a Great Blue Heron)?

The Bluegill have spawned by now and even 10/day wouldn't impact the overall fishery. As a percentage of the fish in the pond, it's a minuscule amount.

But, we still need to figure out why. Water parameters look good. Any significant water changes lately (temp could do it) or any other stressors happening to the fish?

Angling and handling the fish could cause that too.
