I tried to candle my eggs on day 4. Couldn't see a thing. I put a quarter-sized hole in a shoe box, then cut a hole in the side and slip my lamp lightbulb in the box through another hole and put the box down over it. The light was very bright and I set the egg over the little hole, but couldn't see a thing. Was very disappointed, so now I have to wait until I smell something bad coming from the bator before I know anything? How will I know which egg is the offender? Should I pick each one up and whiff? My eggs went in the incubator at 7:30 a.m. on Thanksgiving Day. The humidity is between 38 & 40 % and the temp is at a steady 100 degrees. Depending on room temp, the temp in the incubator fluctuates from 99 to 100.5. However, when I first put the eggs in the incubator, the temp fluctuated from 98 to 102, though not for extended periods of time. Possible 1/2 hour to 1 hour, the incubator could have been at 98 or 102 degrees. Has this killed my babies - do I need to give up? Thanks for any info.
