Hello friends, I made a incubator by myself and made two hatches. The pic uploaded is my first chick from my second batch of incubation. In the first batch i got 8/10 and in the second only 6/9. The chicks are mostly dying at the last days of incubation. I can see fully grown dead chicks inside the shell.l have also uploaded the pic of the fully grown dead chick inside the shell. What are the things I need to follow to increase the hatching rate.
