I have spent the past few days looking around and now I'm more confused than when I started. I have a little giant still air incubator and I have found that the desired temp at the top of the eggs is 101.5. I'm just wondering though, what are the plusses and minuses in variation at the top of the egg? For example: If the temp at the top of the egg is supposed to average at 101.5, is it ok for the temp at the top of the egg to get to 102.0, 102.5, 103.0 or higher? Also, what are the lower limits? I'm guessing that there would still be preferred variation of +/- 1 degree (say 100.5 to 102.5) but I just need a little conformation!
