It depends on the specie of the bird. Try posting another question including something on the specie of the bird.
It takes about 8-10 days to open.
It takes about 12-14 days for a robin egg to hatch, depending on factors such as temperature and humidity. Once the egg starts to crack, it can take a few hours to a day for the chick to fully emerge.
It takes about 10 to 14 days for a miniature to open their eyes. Sometimes it will even take 8 days.

Puppies are born with their eyelids fused together and are blind. They normally open their eyes at 12 days old. All puppies are born with blue eyes btw! When they first open the eyes should be protected from bright light, they have very limited vision at first and basically can just see light and shadow. They are also born deaf, with ear canals closed. They begin to hear at about 10 days. Actually it takes anywhere from 1-2 weeks for the puppies to open there eye's! Average is about 9 day's old! And there ears will open a few days after the eyes do!
