I've got a hand-me-down Hova-Bator 1620 that I'm using for a dozen random breed eggs we got at the local feed store. They were set on Tuesday night and overnight i had a temperature spike to 105 in the early hours of the morning. I got it under control and read a LOT about the possibility of them being cooked but I'm just going to patiently wait until day 10 to make any decisions.
But I've got some questions:
1.) I now know not to follow the instructions that come with the Hova-Bator. But I'm unsure what temperature I should have it at now that I've seen several different temps listed for styrofoam still-air incubators. Some say 100, some say 99.5, some say 102. My thermometers are both reading the same within a half degree so I know I can get an accurate temp if needed, but what should I truly be aiming for here?
2.) Humidity: I've got a digital hygrometer that I calibrated with the salt method. It's reading about 12 percentage points LOWER that the analog dial hygrometer I've got in there, which was reading at 60. I got the humidity to read about 50 on the analog, and the digital is reading 37-38. What can I make of that? Should I assume something in the middle? Should I trust one over the other? What would you do? (Oh, I've been moving the hygrometers around the incubator, too, placing them lightly on top of the eggs to get readings there and they are pretty consistent all over the interior.)
3.) I'm turning the eggs 3-7 times a day and making sure they are resting on alternating sides each night. I'm reading here not to rotate them? Because loose air sacs? I don't quite know what that means. Should I worry about it? Is it something I can avoid? Trying to find the beginning of that convo in the thread so i can learn more...
4.) Are there any other tried and true instructions for using this model that differ from the manufacturer's instructions (besides humidity, I think it's pretty clear I should not use the tray!) or that might not be obvious to me right now? I'd appreciate hearing it!
Ok, now off to read every page of this thread. :) Thanks!
