You seem to know just about all there is to know about incubating as well as grown chickens, and I respect your advice, and everyone else's. I read in a book called "How to Raise Chickens",that you should let the incubating eggs cool for about 20 minutes a day, as the mother hen leaves the nest for about that amount of time each day to eat, drink, defecate, etc. What do you think about this, and have you ever done tried it? I'm incubating six eggs and am wondering if I should try letting them cool like the book suggests.
