The eggs should of chalked within a week. When the eggs are first laid they're yellowish. After a day or two they start out with a white spot that spreads till the egg is eventually all white. If yours didn't do this then they're probably not fertile. Here's a pic of some of mine chalking. Notice the egg on the far left, it was not fertile.i just pulled my RES turtle eggs into incubation, on first day it dented a bit, a week later the egg is nearly half dented, does that mean eggs were not fertile? How early can you tell?
