Candling question

[Bird Brain]

I have an egg that I am not sure about. When I candle it it looks like there is just water in there. It also kinda has a bubble that resembles what I guess a double yolker looks like. I wanted to wait to chunk it until I got input from yall.

How old is it? If it was just laid it would be OK to eat but would discard for hatching purposes.
