Robin eggs. The female typically lays two to four light blue eggs - about the size and weight of a quarter (see photo). The female incubates the eggs over a two-week period and both parents care for the young. The eggs take around two weeks to hatch and the chicks will fledge when they are about 12 to 14 days old. The female may produce two broods of young each year.

Day fifteen since I discovered the robin's nest under my bedroom window. It's been fourteen days since the first egg was laid. Today, the mama bird refuses to leave the nest for our photo session.
