I have been getting a reasonable hatch rate, but I am also having a number of eggs which are peeped but then the bird cannot get out and eventually dies. I pulled a peacock out last week. It seeemed to have a thin film all around except where it had pecked and could not penetrate it. Once i cut it, I was able to peel it without any damage to the chick. What am I doing wrong? Too hot? Too high a humidity or too low a humidity? Please give me your thoughts and experiences.
