Small crack in egg

[Pikori]

My society finch has a clutch of 5 eggs. I recently candled the eggs since the incubation period was near the end. I believe all 5 are fertile since I see networks of blood vessels within each one. But after I had candled them, I took a peek inside a few hours later, and there seemed to be a crack in one of the eggs. The crack is VERY light and thin and I would not have seen it if I didn't candle them again. I believe I may have disturbed this egg while I was candling.

I was wondering if I needed to take measures on repairing the egg since the crack is literally a line and everything is still intact. Would even a small crack such as this one affect the baby inside? I have researched about repairing eggs and I understand the procedure, but I was wondering if it was necessary, or if it would actually do more damage to the chick.
