Advice on my eggs

[Delboyoneleggedturkeys]

Hello everyone new to incubating egg's some white some blue on day 8 i can see small black dot and red Veins on all eggs but on the blue (Cream Legbar) eggs one side is a dark shadow. But on the white eggs (peking) there is a Shadow but not as distinctive. Any help or advice please

Pictures will help.. if you see veins they are fine. So.e eggs are harder to see until later
