Candeling Eggs

hey i thought these were very clear pictures of the difference between a fertilized egg and a non... as this was a recently layed egg it could either be fertilised or clear as it's too early to tell but i took the picture of it to show the clear difference for people interesting in candeling their eggs without knowing what to look for... the second egg is quite far on in the devolpment of the chick so don't expect all eggs to look like this but it was a rather hard job taking a picture of the veins developing inside but atleast you have some idea what to look for:)

(clear looking egg too early to tell or unfertilised)

(clearly fertilised well developed egg)
