Thank you Roxanne and Brooke, I am going to Walmart in a few. Lets see 4 eggs if they ALL hatch, only cost me about 47.00 each, lol. Dang it!!!Go to walmart and buy a glass bulb fish tank thermometer($2-$3.) These are easy to calibrate. Just fill a glass with crushed ice and then add water to the top. let it sit for a few minutes and then stir. hold the thermometer in the middle without touching the sides or bottom. Within a minute it should read 32 F or 0 C whichever it is. If it above the 32 just subtract. If it is below then add that number to get you to the 32F.
