Help -- Dead Chicks

[skeleroo]

I have a brinsea mini advance that I've had for quite a while now and have never had any issues with. I hatch my own chickens' eggs and I've also never had any problems with them, either.

But today I've got two dead chicks.

Last night I took out two early hatchers and put them in the brooder. This morning two more were working their way out of their eggs. By this afternoon one had fully zipped and was just about to pop out and another had zipped >3/4 of the way. But when I went to check on them a little while later they were both dead.

There were no deformities to the chicks. Everything looked good. The brinsea didn't tell me there was any temperature fluctuations.

I'm baffled. And very sad. Any suggestions?

Scratch that. All five of the remaining eggs have perished. They were all alive and chirping this morning.

So disappointing.

Did it seem like there was a lot of fluid in the eggs? Possibly as the chicks rotated they could have drown in fluid...?

No. They were all hatching. The two were almost fully zipped and the other three had pipped into the air sac. I can't explain it.

That didn't answer your question at all.

There wasn't a lot of fluid in the egg. I was almost concerned that maybe they had shrink wrapped but everything looked really good.

Could it be contamination? Dirty incubator? Over sanitized? Water/humidity contaminations?

That just weird that all 5 died, was the Brinsea fan running? My Brinsea had this happened one time after the successful hatched and when I set it up for the next hatch the fan connector dislodged so there were uneven temp and humidity in some areas, without the sensor reading it, lost a few of eggs and chicks.
