I opened my eggs this morning. I did the float test last night and there was no motion so I decided to see what was in one this morning. Nothing. So I proceeded with the rest. My best guess is several things must have happened during incubation because of the varied stages of development but darned if I know what that was. So, here's the run down and maybe someone can help me. Out of 24 eggs 2 which I discarded during float test because they were upside down, I figure the air sacs had a problem or something. The kids opened them in a plastic bag and there was no development. 6 had large yolks with beginning development. Fully developed legs and everything but the bird definitely had a ways to go still had heavy veining in the egg. 5 looked ready to hatch with a tiny yolk and no noticable veining. They really looked like they could have just fluffed up and been ready to go. It just breaks my heart. The rest were just yolks. Nothing smelled. The lady I got them from had tested fertility and guaranteed her eggs and said she would replace anything that didnt hatch so I don't really feel this was a fertility issue. I think it was an incubation issue I just wish I knew what happened. I feel the meter I used for reading was accurate because I spent extra and got a thermometer used for humidors not just a garden therm/hygr. I think what might be the problem is that since we heat with wood the temp swings in the house vary too much but I'm not sure. I keep the incubator in the living room and I fear that when I wasn't home the kids may have gotten the fire too high and the temp may have spiked. That's the only thing I can figure. I might try again and put the incubator in my bedroom. The room is cold but at least it is consistently cold. Better luck next time I guess.
