Thanks. I'll find one of the air cell guides.
Thanks, it sounds like Porter likes lower temp during hatching. I have been matching the temp in my hatcher and incubator. Due to my early hatches I lowered in incubator temp from 100 to 99.5. I'll lower my hatcher to 98.5 and leave it's humidity up and see how things turn out for this weeks hatch and next weeks.
Thank all of you for your help and suggestions. I'll keep you updated on results.
