Eyes/Non-crusty Blind guinea pig?

So our pregnant foster piggy had her babies a little over a week ago, and as I've been observing the babies, I'm nearly positive that the littlest is blind. We took in this pregnant female, a male, another female that had just given birth, three babies, and one additional female about three weeks ago from a hoarder who was letting them all live together in a cardboard box. The mama that just had her babies was nearly identical to the male, both white with the exact same black ring around their eyes; this leads me to believe that they were related, and were allowed to breed. As much as I had my fingers crossed, I figured there would be some sort of health issues with the babies.

The baby in question is all white, and super, super tiny. I noticed right away that the others stick to mama like glue, but this one is often off by herself crying loudly, like she can't seem to find her group. She doesn't knock into things, but when I put my hand anywhere near her, she doesn't flinch a bit like the others do.

I know if she can't see there's nothing we can do about it, but I just wanted to see if there are any special things I would need to do for her? She seems to be getting to the food and water fine, and she's got a good appetite. I'm assuming that blindness is just something she'll adapt to, but I want to make sure if there's anything we can do for her that we do it.

I was planning on adopting out the babies once they're old enough and keeping the mama with the rest of my girls. She's a chirper whom I've grown extremely attached to, and the cutest thing. Now after thinking about it, though, should I still try and adopt out little one or should I consider keeping her?

Any advice is greatly appreciated! Thank you!
