Only 1 chick hatched three incubations in a row

The Amazon listing shows it pulling the air upward in the diagram so the fan’s direction appears to be deliberate.

I honestly would be putting more holes into the incubator myself or I would be looking into a new incubator. It sounds like it is an incubator issue.

Are there any reviews on this incubator where people are having the same issue?

 

[Florida Bullfrog]

Actually yes, on Amazon there are a few reviews that mention losing batches after a degree of development. This incubator was a gift, not one I researched myself before purchases.

Where would be the best place to add some ventilation? I don’t mind modding it with risk of damaging it. Its not doing me much good as it is.

 

[FortCluck]

Humidity and heat go up so you would want to put it at the top somewhere. I would tinker with it a bit and add one hole then test out the incubator then add another.

I was just reading the reviews too. Seems like some lost them due to temperature.

I have numerous holes on the top of mine and I don't close any of them during incubation

 

[Florida Bullfrog]

I see now that there are small vent holes on the top (4 holes) and this must be where the unit is supposed to vent from.

When I was gifted with the unit I read about the issues with temperature control so I made sure the calibrate the unit’s thermometer. It seems to reasonably hold a stable temperature at standard room temps.

How many vent holes are there?

Just doesn't seem like there are enough

 

[Florida Bullfrog]

4 of those small holes. That’s all. Looks like drilling them out would be easy. What would be a good size?

 

[FortCluck]

The bigger ones on mine are about a 3/8 drill bit size. I think that any size would be fine.

Is the incubator plastic? Just try not to go through any wiring.

 

[Florida Bullfrog]

Yes the incubator is plastic. I have a couple of eggs in it left from a brooding hen who didn’t wait for them to hatch. After they’ve had time to hatch and my incubator frees up, I’ll make the modifications. Based on the incubator designs I’ve studied since this thread, I’m all the more convinced this incubator was designed with poor ventilation and that would be the likely reason for the bad experiences mentioned in the Amazon reviews across the various Janoel 10 clones.
