Possible Air flow problems

[Knighstar679]

Hi,
I have been trying to incubate a set of eggs for about 10 days. I had been seeing darkening in the dark (nothing like a blood ring) so i left them alone in this incubator i had barrowed from a friend.

The thing is despite the temp and humitiy being where they seemed to need to be for my eggs, i have seen almost no development in them. They have been rotated 5 times a day. My concern is this incubator doesn't seem to have a lot of great in and out air floor. Could that be effecting my eggs, and at this point is there anything i can do to save them? I put them into a homemade incubator which as far as i can tell is doing better than this one at this time as i have a couple of eggs showing veins. Only reason why I didn't put these eggs in there is because i thought they would have a better chance in a professional incubator than the one i just kinda have been learning about as i go.

Is it still air or forced air?
Is the temperature guaranteed to be at 95.5 with a calibrated thermometer?

I want to say it has an internal fan of some sort but I really don’t know. I don’t remember reading it had a fan.

I wasn’t aware to use an external temperature reading from other than the incubator until I was reading on here today. I will be getting one tomorrow to see for sure.

Can you hear a fan blowing?
The difference between still air and forced air is that warm and cool air stratifies if it isn't moving. In a still air, the incubator should read 101.5 at the top of the egg. That should make it 99.5 at the midpoint of the egg which is what it should be in a forced air incubator.

I included a picture of the incubator that I am having issues with. I know these are supposed to be awesome incubators but I am worried the eggs themselves are not getting enough air exchange. They had change from the day I first put them in until day four or five then they stopped.

If I take those eggs and put them in another incubator what are the chances that I will see any hatch out of it?

The incubator you are concerned about is the Mini-Advance? Did you follow the instructions? If other people hatch with them, they must have sufficient air flow.
Without getting deep into the science, the eggs do better with higher carbon dioxide concentration the first week. That's why some of the Styrofoam manufacturers recommend leaving the plugs in the first few days, remove one and a few days later remove the other one.
Second half they do need plenty of oxygen.
So leaving the concern about air flow out of the equation.
The number one reason for failures are uncalibrated thermometers and reliance on the digital reading on the incubator - they are usually wrong.

I followed all the instructions. I am going to guess the temp reading is wrong.

But my question isn’t about the incubator it’s about the eggs. Could they still hatch if put in a stable heat source with good humidity and air flow if they were in that incubator for nine 9 with it being off?

If the embryos are still alive, they can still hatch with all correct parameters.
Depending on the color of the eggs you may be able to see movement when candling.

 

[Knighstar679]

What do I look for to make sure they are alive? None had made it to the vein stage yet.

Are the eggs white or another color?
What day are they on?
Look for movement in the embryo.
I really can't see much in my dark eggs so unless I have a leaker or stinker, I just leave them till they either hatch or don't.
