Kvod harav how how can one eat boiled eggs if eggs need to be checked for blood?
Eggs in our times do not need to be checked for blood spots. This is because egg farms do not keep roosters on the farms, to prevent any of the eggs from getting fertilized. The reason one checks eggs is to see if there is blood, which can only occur after getting fertilized. It is praiseworthy to check eggs if one is opening them raw, however it is not halachicaly required.
All the best
