Ok so I recently had 24 eggs in the incubator. I had 10 hatch and live. 2 were total duds. 5 died in incubation. Now here is my problem, 7 of my chicks pipped and did not make it much farther. I use a styrafoam still air incubator. There are 2 plugs in the top. We leave both in for a week, open up one at the begining of week 2. Then when there is a week left we open the 2nd plug. What am I doing wrong? What else can I do to make things work right so they actually make it farther than the pip.
