I found a spot of blood in an egg; was there a chick developing?


We do not keep roosters in our laying barn so it is not possible for an egg to be fertilized. Unfertilized eggs cannot develop into chicks.

Eggs with blood spots occur in about 1% of eggs. When a yolk develops in a hen's ovary it is enclosed in a sack containing blood vessels. When the yolk is mature it is released from an  area of the yolk sac that has no blood vessels, but occasionally the yolk sac ruptures, causing blood vessels to break and blood to appear on the yolk or in the white. Although they are perfectly safe to  eat, eggs with blood spots are usually removed from the line during inspection for grading. Small blood spots are difficult to see, especially in  brown shells, and can sometimes be missed.
