My son's 7th grade science class is trying to hatch eggs. I purchased the fertile eggs from a local farm and they were set on April 10th. They purchased the incubator this year from a school supply catalog. It is made of styrofoam and the temp seems high to me (sometimes at 105), of course, who can say how accurate the thermometer is?? My question is this: Can anyone share a success story with me about one of these educational incubators. I am just worried that the only education that may come of this is that THEY DON'T ALWAYS HATCH??!!?? Thanks in advance for any help/advise.
