Ok, so I posted a forum a little bit ago and got tons of help. But, one things that I'm still not sure of is how to measure the humidity level correctly. It is supposed to be round 65-70%, correct? Do you even need a hygrometer? I read about putting flat rocks at the bottom of the water slots along with food coloring so you know when you need to refill the water. Rocks are supposed to store heat I guess. During the "lock down period" are you supposed to bump up the humidity level to 75-80%? Candling is another big thing. Every day, once a week? I have a sheet printed out on the stages and stuff but how long can you keep the eggs out of the incubator? Thanks!
