So my camera on my phone isn't capturing much of the scarring so I can't post any good pictures.

My female albino is about two years old, 600-700 grams and feeds live small rats weekly. Recently I've been getting rats delivered by a friend and she was unable to deliver for three weeks and I have no other source of food for my poor albino. She seemed fine though, still does, although yesterday I noticed some pretty drastic cuts all over her sides and face, one huge one deep in her snout and it looks like its almost cutting a heat pocket which worries me, and she also has these weird brown marks dotting along her spine and only her spine. She's currently in shed so I thought it was shed skin but I tried rubbing it off with warm water and it wouldn't come off. It's all over her back. I've been searching for an hour on the internet and can't find anything regarding these marks, or I may just be overthinking it. A friend said that she may have just been roaming quite a bit in search for food but there's nothing in her enclosure that could scrape her, or so I think, and I tried feeding her the other day and she killed but didn't eat it.

The only other thing I can think to add is that a baby ball of mine passed away a couple weeks ago, but I don't think he was ill. None of my other snakes are showing any signs of anything either, like this thing on her spine.
I really hope someone can help.
