Please, please, please do your research. You will need to know the basics before you plug that thing in and set your eggs. Use BYC's search feature. Know about temps, humidity, turning, number of days for what you are hatching, how to lockdown properly. I have seen too many posts lately with people who just plugged it in, set the eggs, THEN come here and ask questions that should have been answered before they started. Gather your information prior to starting and save yourselves many, many panicky hours.
