Okay, I am over my losses and thinking about the rest of them now. The last silkie is making his way out and the other hatchling is doing just fine. The potential problem lies with the guineas.
If all but two of those eggs were shrink wrapped, it stands to reason that the problem lies with the humidity level in my incubator. That makes no sense though, as I calibrated my hygrometer before I used it and my humidity never got too low. Of course, they all seem to have died over the last few days, as they were all fully formed, short of a few. I didn't push the humidity up the way that it is "recommended" as I didn't want it to have a negative effect on the guineas that have more time left... Ugh...
The humidity, right now, is running at about 54%. Do you think that I should crank it up to help to avoid another issue? Will too much humidity be bad for the new chicks? The thing that really stinks about the guinea eggs is that I am not able to see through them well enough to know what is going on, come hatch day!! lol
