The mother laid the first egg on 25 January. The next two eggs came on 28 January and 31 January. The pair have taken turns keeping them warm.
Jackie has lost roughly a dozen eggs and eaglets in over 10 years in Big Bear Valley, raised three hatchlings and fallen for two mates.
A webcam is constantly recording the birds of prey and their nest, which is perched high above the mountain community of Big Bear.
A Friends of the Big Bear Valley Facebook post states: “Jackie and Shadow are running a smooth well-organized household for their new ‘party of five.
“They could have three little newly hatched chicks scurrying around the nest in just about a month or so.”
