Welcome to BYC.
If you share a little more information about the process you have used we can try to help you. Knowing the type of incubator you are using, what your temperature and humidity readings were during the process, whether you were using an auto-turner or hand turning, etc can all help. Did you calibrate your thermometer prior to placing eggs in the incubator? When you did the eggtopsies at what stage did it appear the chicks had died? Did you see any evidence of internal or external pips indicating that they had reached the point of hatch?
