I made me one of those homemade incubators out of an old ice chest and have tried two batches of my eggs. So far nothing. I'm 10 days into batch number two and not an experienced candler, so can't say for sure, but it looks like I killed all the eggs. I would really like to figure this out before my turn comes around for some nice, purchased eggs. I don't think it's my eggs. My one broody hen had luck with them, so I think I'm doing something wrong. It's a forced air incubator, air temp ranges between 97 and 102. Water wiggler temp is 99 - 100. Humidity is between 30% and 40%. Any ideas?
