baby coturnix hatched without absorbing all of the yolk sack....

[lagpmgdsls]

Whats its prognosis? Should I do anything?

The best you can do is allow it to rest. Many times they will still absorb the Yolk Sack after coming out of the egg.

Good luck with it,

If it's not too major, they can survive and absorb it sometimes. Keep it right in the incubator at incubator temperature, try to keep something soft and cushioned like a towel in the bottom so it can't rupture the yolk sac on a wire mesh or something, and try to keep it clean and hope for the best. You should know in about 24 hours.
