i manage to obtain a 60 % icubation rate. problem is that infertile eggs were to few. i opened a few eggs and the problem is that embrion seems to be fully developed, (so is a late death) but they dint pip into the "air room", so they die in the shell probably becasue asphixiation. what's seems to be the problem ? humidity, airflow ? i will put another series in 1 week, and i hope i will do better. thanks.
