x2 You don't want your humidty that high for the first 17 days. And those manuals are ONLY good for telling you about the product, not about hatching. I also recommend considering dry hatching and learning about why we control humidity and how to tell if your humidity is working for you. I can send you some info on it if you would like.Please, before you let an other day go by, read the information in the learning center regarding "dry hatch". Lots of chicks are killed by following the instructions that come with an incubator! You'll get a much better hatch keeping your humidity down to around 30% during the first 18 days of incubation. Read all of the information in "Hatching 101" and you'll have a much better idea of what's going on and how to optimize your hatch. Most important: calibrate your thermometer to 100*, and keep that humidity down until lock down.
