Question
I see that you answered a question someone asked about blood spots in eggs.  You said that this means that the egg has been fertilised.  THIS IS NOT TRUE.  I keep chicken which run with roosters and we eat the eggs daily and NEVER find bloodspots in them.  However I also  work on a poultry farm where there were no roosters and we  get blood spots in the eggs.
So your reply was either a lie, or you made it up or for whatever reason you do not know the answer then you should not give answers if all you can answer is fiction!
I suggest that you either get your facts correct or just admit that you do not know.
I look forward to your reply but I bet I dont get one!

Answer
Hey margaret.  Why are you so hostile? I was not lying. Why would I do that? The presense of blood in a bird egg indicates that there is a developing embryo and a developing embryo means fertilization.
You mentioned that you eat eggs from hens that are with roosters and there are no blood spots. Either this is because the eggs are infertile or they are collected before the embryo starts to develop.
As to why there is blood in an unfertilized egg I do not know.
