The hatching journey of chick number 3Jackie laid her third and final egg on January 28. The average incubation period for a bald eagle is around 35 days. So, there on March 6, a snowy cold morning in Big Bear, at 10:21 a.m., the first pip, or crack, was spotted.By 10:53 a.m. it had grown. The hatching process typically takes a couple days, and the snowy conditions kept Jackie firmly on the nest to keep her chicks warm and out of sight. Two days later, at 2:11 a.m., a new chick was visible, but not quite out of the shell. By 6:13 a.m., chick number 3 had completed its journey and was present for the early-morning feeding.Since its birth, chick 3 has received multiple feedings from its parents. Its eyesight is still developing, so sometimes it takes a moment to get situated.It has also experienced some danger: Ravens have attempted to infiltrate the nest, but Jackie called out to Shadow, and the parents worked together to scare the intruders away. The neighborhood flying squirrel, Fiona, also tried to visit, but Jackies wing slaps got her to mind her own business.Chick 3 will have to learn to get along with its siblings. Its normal to see some jostling around as one chick emerges as the dominant sibling. They will also bonk each other on the head but soon find their rhythm and, uh, pecking order.At around 10 to 12 weeks, these eaglets will fledge, or leave the nest, for the first time. They typically hang out close to home for a couple months before they completely strike out on their own.To catch them before they fly away, check out the webcam embedded here.
