Do you have the 20 Advance, or the 20 Eco? The Advance shows temp and humidity, the Eco doesn't. Both are calibrated at the factory and from what I have read are usually very close. I had to raise my temps by 0.5 degrees after 2 delayed hatches. If you have an Advance with a turning cradle, fill one water channel, load the eggs between the dividers, then set the tray into the incubator and set the incubator on the cradle. It's a very simple incubator to use, and requires very little babysitting. I do recommend getting a second thermometer/hygrometer to double check temps and humidity. If you have the Eco model, then you definitely need to do that.Could someone on here give me a step by step guide on how to use my octagon 20 advance? I read the instructions it came with, but I don't quite understand all of it. It doesn't show the humidity, so is there a special way to check it? And do I manually need to turn the eggs every 24 hours?
If you do have the Eco, loading it is the same as above. You will have to turn manually, but that's why the Octagon is shaped like it is. You don't have to turn the eggs individually, you turn the entire incubator back and forth on the flat edges 2 or three times a day.
Both have an air vent on the front that is used to control humidity. To raise humidity close the vent, to lower humidity open the vent. Never close it more than 1/4 open, the eggs and chicks need the air flow. That should get you started. Feel free to ask more questions. We Brinsea users love talking about them
