You're farther north than I am, but here in Missouri the first bluegill spawn will be sometimearound the new moon in May. Don't be too afraid of taking some of the spawners because bluegill will spawn once a month from may through july. I'm thinking here it will be about the 25th or 26th.
The males will establish the beds and I'm pretty sure the silly things will tend any bed that happens to be near.....so if you take one, all isn't lost.
