This is the first time I have tried hatching. I got 42 (presumably) fertile eggs from my mixed flock of easter eggers, red and black sex links, barred rocks, white leghorns and silver laced wyandottes. Put them in my LG incubator (still air, no fan) and followed the directions which came with that incubator.

The incubator is in a room with a steady temperature of 66 degrees which is within the specified range of 65-72.

First, I am having no luck keeping the incubator temperature steady at 99.5. Before starting incubatiion, I got the temperature at 99.5 after three days of adjustment of the thermostat. Then I started incubating. That was 12 days ago. I check the incubator temp daily and it's been as high as 101 and as low as 98. Each time I barely tweak the thermostat to try to get it back to 99.5 but even if I get it there, by the next day it's not there anymore. I am pretty sure it's not me, it's the incubator / thermostat. Is this typical with the LG incubator? Should my eggs be OK despite the inexact temperature?

Second, I candled about half the eggs on day 9 but I really had a hard time telling which ones were viable. My eggs are all different colors ranging from white to dark olive to light brown to dark brown. There were a few where I could see an embryo but most I could not because there just wasn't much light getting through the dark shells. I was using a work light in a cardboard box with the hole cut in the top of the box so I don't think the fault was with my candling system. Just to be on the safe side I put all the eggs back in the incubator, where they remain...is there any risk to doing this or should I candle them all again and try harder to tell which are viable? Any tips on candling eggs with dark, thick shells?

Thanks in advance.
 
People are going to slam LG bators in their replies, but I started with one many years ago and had perfect hatches. I use an HB low end 1602n which is pretty much the equivalent. Mine was extremely difficult to get stable during the first hatch I attempted. This changed when I added the auto turner and fan. Fan did it all, to be clear. Do you have a fan?

Candling is difficult to accomplish successfully for the untrained eye. And you need a high powered candling unit. I use a 200 Lumen flashlight and you can pick up a multi bulbed flashlight at a drugstore for cheap. This is key for the hard to candle eggs (i.e. copper marans, EEs) I am successful with coturnix eggs, too. People will say day 9 is early, but it is possible to determine viable eggs early on. Again, it's the experience. You will be more definite on around day 13.
