From all the information I've read so far, it says the temperature should be in the 99-100ºF (37.22-37.78ºC) range (forced air). In my incubator's user's manual, it says the temperature should be 37.7ºC (99.86ºF) until the 18th day, and should be lowered to 37.2ºC (98.96ºC) in the last 3 days. I've never hatched eggs and I'm considering doing it in the next few weeks. Howerver, I can't find anywhere, except in that manual, where it says that. Could someone who's experienced in this kind of things please tell me whether it should be done this way? Thank you.
