Guess when the puppies eyes open

I thought it might be fun to have a guessing game with a prize!
The babies still don't have their eyes open, it seems like it's overdue, but they aren't as squinty as they were a couple of days ago.
They were born on the 21st of February, so they're almost 14 days old.

Anyway, leave me a comment with your guess, and the closest one wins this bead. It's a large lentil, almost an inch and a half across, so very suitable for a focal piece. In the case of more thsn one person guessing the correct day, I'll take the first comment with the correct date.
