This is my first time hatching any eggs. These are chicken eggs. I bought a used incubator, and also a new one. Styrofoam type--for hobbyists. Today is hatch day and I've been a nervous wreck the past 3 weeks. I have two frustrations. #1 is not being able to find a thermometer with decimal places. The used one didn't come with one. I did find a nice thermometer/hygrometer at Wal-Mart, but again it's whole numbers. #2 is that it's darn hard to control the temp. I've been staying at 99 rather than 100, as the optimal temp for chickens is 99.5. If I turn that dial ever so slightly, sometimes it's either 97, 100, or 102 and nothing in between. Even if I do get to 99, which I've succeeded at quite a bit, I'm never sure that that's exactly where I want to be: is it 99.4? 99.3? 99.5 would round up to 100, but 100 is too hot for little chickies. Some of the eggs are rocking in shaking in my new incubator, the hatching one without the turner, but I don't see any pips yet. I'm fearing I haven't controlled the temp, or even gotten to the right temp, and none will hatch. Please help, and thanks in advance. If my hatch doesn't turn out correctly, I want to know how to do it right, because I'd like to try again. Surely it isn't this hard.
