[FONT=Verdana, Arial, Helvetica, sans-serif]Blood spots occur when blood is released along with a yolk from the hens ovary. Each developing yolk in a hen's ovary is enclosed in a sack containing blood vessels that supply yolk building substances. When the yolk is mature, it is normally released from the only area of the yolk sac, that is free of blood vessels. Occasionally, the yolk sac ruptures at some other point though, causing a blood vessel to break and blood released will be encased in the egg with the contents. It most often appears on the yolk, but can sometimes be seen in the white. It does look unappetising, but the eggs is perfectly o.k. to eat and the little blood spot can easily be removed with a knife before you cook it.[/FONT]
