I have been reading up on this a lot, but many people say different things. I am hatching eggs in an incubator for a science fair project. It is a little giant still air, no turner. I have been turning the eggs 2-3 times a day and have been keeping the water reservoir full. What is the best temperature for hatching chicks? The eggs are regular chicken eggs from a friend. Am I allowed to open the incubator during lock down to remove the chicks that have hatched? I have hatched chicks before with broody hens, and have done it in an incubator once, but that was not for hatch rates, just to save some abandoned eggs. I am new to backyard chickens, and actually got an account to ask for help on these questions. I need at least a 75% hatch rate for the science fair to work.
