Sounds really good to me! I've got four foam incubators, two still air and have trouble keeping a steady temp.... Usually around 100 but I have different thermometers and they all are a little different. Planning on "checking" them as well as the hydrometers as soon as the last three hatches are finished. Just had five bantam silkie and silkie mixes hatch on days 19 and 20 which I understand is typical.. Tomorrow is hatch day for a bunch of cochins, buff orpington and dominiques. I'm really stressed about this hatch as the crappy thermometer that came with the incubator is running a lot hotter than the thermometers I bought. The ones I bought are lower and with the eggs and running at 100 approx. but the other is 102.....(higher and closer to the top).. Enough to make one completely nuts...
