You should read the article "Hatching Eggs 101". You will find it on the right side of the "incubating and hatching eggs" forums. You want to go most of the way down the page to the section titled "Lockdown" in big red letters. It will give you the best information that you can get as incubating and hatching have many variances and no one can give you the exact information you're looking for.
Please make sure to not open the incubator anymore and to get your humidity up to 65% to allow your chick the best opportunity of hatching.From what I can understand with your chick, you "can" have anywhere from 1-2 days before this baby can hatch.
Please read the article.
