Good morning! I'm new to this site and to incubating eggs. I'm on day nine today and most of the eggs appear to be progressing nicely. I just got a backyard mix of 48 eggs from Craigslist. My problem, I'm having trouble finding a good thermometer. Between both incubators attached digital thermometers and the three that I've bought, not one of them read the same. I have no idea what, if any, thermometer is reading correctly. Any recommendations on a good accurate thermometer? Also, some of the eggs I got are really porous. I'll try to attach a picture. Question, should I continue to try to hatch them or should I just toss them? I can't even really see inside the eggs when I candle because of how porous some are. I appreciate any and all advice!
