Tracy The Chick....I just want you to know I set all single yolk eggs, 16 of them. I got to lockdown last weekend and the first one pipped right on time..........and I killed all the others. I had started a staggered hatch so today I am in lockdown again. I hope I don't kill all of these. There are 12. AND I did an experiment with two of them and put them under a broody hen who was sitting in a feed bucket. I took them away on day five because it didn't appear that she was turning the eggs and put them in the incubator. So I'm experimenting with my eggs. I feel bad I killed them. It certainly wasn't anything I did intentionally. I did read a lot of information about how to incubate beforehand, but obvioulsy I messed up. I held my little chickie I had to put to sleep and told it I was sorry. I take full responsibility. That being said, I'm going to keep trying and hopefully will figure this out. So what if you meant to set them or not. Where would we really be today if there hadn't been great people in the past willing to step out there and try something new? I'm glad you posted and I'm rooting for you.
