Robin's eggs&babies + short video

I discovered American Robin's nest right under my window. First egg was laid on May 18th, then she laid two more eggs. I have been very careful not to disturb the mother since. The first egg hatched on May 30th and second egg the next day. It has been three days since and third egg has not been hatch. It is difficult to take pictures since the window is covered with the blind, but these are the pictures I have gathered.
