From what I can see, you've got lots of veins and a little embryo developing, which are both very good signs Can you see it moving around yet? If not, you'll be able to soon.
I've removed 4 nothing in them 2 looked like they still have movement and 1 chirped but I'm a little concerned as the air bubble is almost half the size of the egg is there anything I can do for this 1 and I think 1 more may have died in the egg but I've left it just incase I'm wrong as this is my first try.
