I'm sorry to hear about the eye problems. It's hard to say what caused it.
As for what to do with the babies..... You have a few choices.
You can give them time to see how they do. Sometimes they don't survive when they're born this way. The survival rate seems to be lower in the Albinos that are born....impared. You might even have to take them to a vet to have the eyes removed. At least, you might have to do that with the ones that look like the eyes are falling out. If they survive, then you can try to find them homes. Hopefully to someone that won't breed them.
You could keep them as pets if they survive.
Or you could.......... well you know. Hopefully, someone will have and idea of the best way to do this.
As to what caused it... Some people believe that Albinos are genetically pron to eye problems. Of course, you have a Het Albino stillborn that had the same problem. So... Mabye temps "partially" caused it as well.
The "theory" is that Het to Het breedings "should" make for stronger Albinos, but that's not always the case. Since it's "impossible" to have unrelated Kahl Hets/Albinos, the best you can do is try to keep the bloodlines diversified.
How were the temps during gestation?? Since this was an unexpected litter, maybe it was the temps.
I really don't know what causes the eye problems. I've seen a couple of "normal" boas that have had the eye problem. They didn't have the Albino gene as a factor. So... It's anyones guess as to what went wrong with your litter.
Hopefully you won't see this problem again.
