I have a baby hognose snake. While weighing her one day, I noticed a portion of her belly scales near her tail were sort of "detached" or flaky, if that's the right word to describe it. One of them rubbed off on my hand as I inspected them and underneath was perfectly healthy, normal belly scales. A couple others came off the same way, with no sign of injury or anything. Beneath the flaky scales was always normal belly scales. The rubbed off scales were translucent, with a tinge of yellow(very little, more like dust). My first instinct was to think of scale rot, but it didn't look like standard descriptions of scale rot(no discoloration, boils, etc). What could it be?

Info if needed: 90 on hot side, 75-80 on cool side depending on time of day. Heating source is rhp controlled by thermostat. Humidity is usually 40-45%. Bedding is aspen shavings to allow tunnels. 2 hides on each side, which she doesn't use very often(she prefers to dig) She eats f/t pinkies every 4 days, though she's a bit picky sometimes. When she's not digesting, she digs around, peeks out from the substrate, and explores. The breeder said that she hasn't shed since she hatched, and I haven't noticed her shedding since I got her, but there was a week-long period 2 weeks ago when she stayed under the substrate and refused to eat.
