Egg suddenly became porous?

[Deo]

Alright so I tried to take a hand at hatching three eggs out. The first one I took right as my hen layed it on the 11th and candled it to check for hairline cracks and pores. It looked good, so I popped it in the incubator.

Now fast forward to today I got a bit impatient and decided to candle it again and there were little spots where the light seemed to seep in more. It seems like the egg suddenly became porous? Does this mean it’s infertile or should I wait till day 10?

I would still wait until day 7 but from my experience it usually means they weren't fertile or just never developed
