I am a teacher, and I am going to hatch some eggs at school. I plan on doing it in my classroom. I was looking for advice from some teachers (or other folks) who have done this before. I have a couple of questions: Should I tak the eggs home on the weekend in case of a weekend hatcher, or is the timing accurate enough that I can know exactly what day they will start hatching? (For example if I start on a Tuesday can I be pretty sure that they will hatch 21 days later on a Tuesday and not 2 days before on a Sunday?) If so will a 30 minute drive with the incubator unplugged be too much and cause the eggs not to hatch. I have some mutts, but is their any particular breed I should try that would have better hatch rates? Any other advice would be welcome. Thanks from one chicken owner to another.
