Terrible focus but you can still see the difference.

Bad egg
19 have veins 1 was yellow with no veins. They all looked good until we pt the light on them. Oh they are almost 1 month along. My fiancée said we should dissect the egg and I thought it would be a good idea until we opened it and it appeared to be under pressure and kinda squirted out a bit. It didn't smell or anything but just seeing milky white stuff ooze out almost made me lose it... aka barf...
Another interesting thing I noticed is that the eggs have seemed to smooth out from when they were initially layed.
