Dwarf hamster, over cleaning wound?

[PurpleKat]

A few days ago we had to separate the 2 sister hamsters we got due to them fighting and blood was drawn. The graze was on her hind-quarters. it didn't bleed much but she's albino so it showed up really clearly.
We let her calm down as she's not fully tame, never bites just skittish, cleaned the wound with sterile saline we had on hand and gauze.
The wound looks clean, scabbed over and fine.
Two days later I noticed blood with bits of fur, in my hamster's tubes that go round her cage.
So I checked the cage for anything different or sharp, nothing.
She does normally clean herself in the tubes, could she be picking at the scabs?

I've had a couple of Chinese recently with skin splits which are pretty much like a wound and on a couple of occasions I've had them knock the scab off from what has been normal cleaning for them. It delays healing of the wound but in most cases they do eventually heal up.

Does your hamster seem like she's cleaning herself more than usual?

She's not cleaning more than usual, but she could be overnight.
It's now been 2 days in a row this has happened, when I see her in the morning.
I've had myself and a friend Just look at her and we can't see the wound been open. It looks the same as yesterday.
