Mike Meyer of WDNR responded with the following information: “Chicks of that age have been documented to be taken by eagle predation, aquatic predators such as snapping turtles, pike, and bass, other loons, and disease. Siblicide also occurs, as we have documented fighting amongst even very small loon chicks. We lose 15-25% of chicks between hatch and fledging each year so the observation on Moon Lake is not that unusual.”
