Once the shell is damage, bacteria sets in and it's all over for that egg. That's if it doesn't die outright from damaged blood vessels or being shaken.
There is 0% chance of that egg hatching. But then again, it was unlikely to begin with that the bird would live to adulthood even if it did hatch.
There was a Robbins nest in my tree and my son saw it and took it out and there was a indent he took his nail and peeled it back now there's a pin hole and it looks like blood but the mother is still coming and everything's normal WILL IT HATCH
