Yes, but the percentage of fertile eggs will rapidly decrease. Was he in good health and mating the hen prior to his death? Lack of health would also affect the chance of fertility. I'd try them in the incubator.
If I remember correctly, the female can stay fertile up to 2 or 3 weeks after the male is gone. Of course, that depends on the last time they mated. It is worth a shot to try and hatch them!
