My first clutch was laid 7 days ago and has been incubating since then. I am using the substrateless method in a 6qt Sterilite container. I was looking at the eggs a few days ago and noticed they were starting to dimple a bit. I'm pretty sure this early in incubation they should not be dimpling.

My incubator setup is a wine cooler (about 3'x2'x2') with 18" of 11" Flexwatt running up the back and a 3" Radioshack computer fan mounted on the ceiling for circulation. My Herpstat is set to 88.5 degrees F and holding very steady.

Do you guys have any suggestions as to what is going on and how I can fix it?

Thanks!
