Thanks for the info! I've got a couple more questions now and then a bunch of info for you. First, a still air incubator has a heating element that heats up the incubator, it's usually somewhat uneven with hot & cold spots throughout the incubator. For a still air, temps need to be 101-102 taken at the top of the eggs. Forced air incubators have a heating element but also a fan the circulates the heat and distributes it evenly throughout the incubator. For forced air incubators the temps should be 99.5. Check and see if your incubator has a fan.
Second, you said that you have pullets. Have they been laying for a few months or are these eggs the first of what they've laid? When a pullet starts laying it is recommended to wait a couple months for the eggs to increase in size and quality before incubating them. But I've always had success with hatching young eggs but they can be a problem. It's good that you're hatching your own eggs, they are much easier then shipped eggs. And obviously they are fertile.
Third thing that I thought of from the info you gave was your humidity days 1-18. It seems high to me but the only way to know for sure if you have the right humidity is to measure your air cells. You need to monitor how the air cells are growing throughout incubation. An easy way to do this when you start hatching is by tracing the air cell with a pencil on days 7,14, & 18. This way you can easily see if they are growing enough. If the air cells don't grow big enough then the chicks can grow to large and drown in excess fluid before ever getting to pip. Air cells should look like this:
I think once we fine tune your temps and humidity you will be on the right track to have a very successful hatch. You can get every egg in that incubator to hatch!!
Now here's the info for you. I'm going to give you 2 links on calibrating a thermometer and how to calibrate a hygrometer. I actually buy a really cheap dial hygrometer for reptiles online for $5. Then I calibrate it before each hatch to make sure it's accurate.
And this article easily explains how your humidity effects your aircells/hatch:
Lastly, I highly recommend reading hatching 101 and reading all the available links. This is basically the bible of hatching and has everything you need to know to have a great hatch.
