veins on day 17 on incubation?

[688peterl]

im on day 17 incubating 2 indian runner eggs...

i can see an embryo moving inside the when i can the eggs (sort of twitching not moving)

but i can also see veins very close to the inner surface of the shell...

why is this? is this normal?

should i still see veins this late in incubation

Sounds like they are doing great. Seeing the veins is fine, I know I just hatched 8 and wondered about it myself but they were all fine.
