A degree or two might not make a difference when you are decided whether to wear a jacket or not, but it can make a heck of a difference when you're incubating eggs for 3 weeks. And yes, they were calibrated (they just didn't STAY calibrated) using the ice and water method - well, all except one that I didn't get the plastic bag sealed up well enough and it met an unfortunate demise by drowning. <sigh>
