As of today, these robin hatchlings are approximately 6 to 7 days old. Now that they are a little older, I can clearly see all four babies. The feathers on their wings poke out like tiny drinking straws before they unfurl. Finer fuzzy feathers are beginning to cover the bulgy eyeballs. Their eyes are starting to open a bit. They only have about 7 more days in their nest. They have lots of growing to do before then.
