Q: What do you do if you find a blood spot in an egg?

A: Now a days, commercial eggs are unfertilized so blood eggs are almost nonexistent, in fact, even if one does find a blood spot in an egg it is probably not the unkosher type of blood spot. Therefore if one wishes to be stringent, he may discard the entire egg (like our grandmothers used to NEED to do); but if he wishes to discard only the blood spot and eat the egg, he has valid halachic basis on which to rely [you should conduct yourself in accordance with your Rabbi on this issue]. 

Q: Does it matter if the blood spot is found in the yolk or the white?

A: According to the lenient view there is no difference, you may discard the blood and eat the egg. According to the stringent view there are 2 customs. The Ashkenazic custom is to discard the egg either way. The Sephardic custom is to always discard the egg when the spot is found in the yolk but not always discard the egg when the blood spot is found on the white [ask your Sephardic Rabbi how to tell the difference].

A: Since the occurrence of blood eggs is rare we do not need to be choshesh (concerned) and are not required to check in such a case [even according to the stringent view]. 

Q: If you find a blood spot in a hard boiled egg does that affect the other eggs boiled with it in the pot?

A: If there were 3 or more eggs cooked with it in the pot then there is no problem with the other eggs [because of the concept of 'batleh b'rov' (nullified in the majority)]. If there were exactly 2 eggs then it depends: If you hold the lenient view stated above then the 2nd egg is unaffected. If you hold the stringent view stated above then the 2nd egg must be discarded since there is no batleh b'rov here.
