How's that egg looking?

That is interesting, haven't seen that.

erm were the brown spots on the right always on the egg?

Both the brown spots and the grey spots do not look good. Have you been candling the eggs to remove any unfertile ones?

Unfertile eggs usually go off, probably around day 16 and before it explodes they can start leaking through the pores.

so sorry to hear sammi, I know how that feels so make sure you figure out what went wrong. Was your temperature steady throughout?
Hope you can figure it out.

Bacteria, did you wash eggs or wipe them down before starting incubation?
