Thanks. Guess I will return this one and get a new one. Should I calibrate it with ice bath then check it against boiling water? I am so scared to trim the fluffy butt and messing something up. I don't really have any help with them so no one that would be willing to hold or trim I don't think so it would be on me to hold AND trim at the same time and I am scared to do that. I swear I saw a bullseye in the egg that I cracked open the other day but it was on the light side but was there so I just don't know.Thanks! I really feel you will be experiencing this soon too! Just maybe in a few weeks after trimming some fluffy butts, lol. Even with all of the crazy readings on the thermometers, you would still see SOMETHING in the eggs. I was just helping a friend last week that was having tons of quitters and when she checked the temp on her incubator (with the wally world meat thermometer I might add, lol!) she found that it was at 92°F. They were still developing but many were quitting and the ones that hatched were of course very very late and weak.
