But when I check the it say around 99.5 more or less. Got a thermometer in the older one. It's designed for incubating. No forced air in the older one.
There's your issue.. at least in part. Temp should be 101.5 -102.. in still air, measured at the top of the eggs not on the floor. I actually like still air and prefer it for the hatching part.
Yes, I would probably bump the temp and give them longer, expectations being low but also knowing that life finds a way! I might also leave the temp and see what happens.. I hate making (screw style) adjustments mid term (gotta make sure it's the right direction, etc).. so maybe do minor adjustment and give several hours to see what happens on the thermometer.. I wonder how far that chick was developed compared to where it should be. Gross pic follows, image from google..
As far as candling goes. Never had a 'store bought' one. But I've tried cutting a hole in cardboard and holding it to a light. I never could see anything.
Inside a
dark space.. using my cell phone flash light works pretty well, depending on egg color and development level. If needed I cup my hand to make the light hole smaller or more focused. I like to candle from the air cell end (and then all around).. and admit it's not my strong point. I've opened a slow developer and had an eyeball looking back at me.
Setting a larger cardboard box over the top.. can help combat swings. As stated by another poster they are designed to work within a specific temperature range.. which my house does not meet.. Adding extra insulation made a huge difference.. be sure the vent holes aren't blocked. I used old blankets etc.. careful also not to cover the thermostat device. (maybe not both??) You might also move eggs around daily to combat warm/cool spots and keep hatch frame tighter.
Shhh. It's a secret. My Wife doesn't want anymore. I plan to surprise her.
Hmm.. I once decided it's easier to get forgiveness than permission. I brought home a mini pig, surprise.. now we have 2 and I've been paying the price since, lol!
Well, it feels good when I know the information *can* be helpful and this has been one of those times, adventure on!
