I definitely agree. Get some separators in that enclosure or completely separate them all together.
I would keep the light on for those snakes. You still need to reach their heating requirements as you do with any Ball.
Those holes you had cut are far too large and it seems a lot of the goo has leaked out. This can not be good as that can dry out the yolk sack.
Usually when incubated at cooler temps it will take longer for the snakes to hatch, so I would not worry. But I would worry about that cut you made. I would add a *little* bit of lukewarm water to each egg so the yolk does not dry out. They could be in those eggs for another week or so being incubated at lower temps.
And also, if a snake it HET for Pied, it means they carry the Pied allele but do not show it because the dominant trait (normal/wild type in this case) overpowers the recessive. If you bred that 100% het Pied to another 100% het Pied or a Pied (visual), you would get Pieds in the offspring. There are markers that can indicate being het for something, but they are not always correct as regular normals can display the markers as well.
If the father is an Albino, then your hatchlings are all 100% het Albino. But, since she was housed with another normal that she could have also bred with, they could just be normals. If you are interested in breeding in a few years, I would suggest holding back one of your hatchlings if one of them is female so you can breed her back to dad. If she is het Albino then you will get Albinos in the offspring being paired back to dad.
