What is this?

[H4ttie]

I’m on day 9 of incubation and this has appeared.
Does anybody know what it is?
Thanks xx

Is it something seeping outta the egg? Whats your temp and humidity

 

[H4ttie]

Yes and it’s gone hard like crystals.
37.5 temp
70% humidity

Take that egg out before it explodes and messes up your batch. Seems like a bacterial infection may have gotten in and its rottening. If you washed any eggs or are using store bought eggs that may happen more since the bloom has been rinsed off allowing bacteria to enter the egg freely. Also your humidity during incubation should be 35-50% and 60-70% on hatch day when you start seeing pips.

Okay, thank you!
