It appears the pair, Bea and Jasper, will have three eggs this season. The third egg was laid March 24th. Ospreys usually lay eggs 1 - 3 days apart. The chicks will hatch in the order the eggs were laid.
Along with the eggs is a photo of Jasper incubating the clutch. Jasper will continue to share the task of incubating the eggs until the chicks hatch, when he will then provide fish for his family.
