Duck Embryo?

[phoenixxflame]

So I've been incubating this egg for about 8 days and saw some small veins on day 4ish. Today, which is around day 8, the egg seems to be fuller, but has no veins visible. I can post more pics if necessary to see what's going on...

The egg still looks viable color wise...have you tried a stronger light..I'm on phone app so hard to judge anything from pic. Hopefully someone will pop in and be able to help more.
