Baby rabbit scaly skin

Question
Hi
my baby rabbits are 4.5 days old now and their fur is starting to grow in. Yesterday morning when I checked them they were all fine, but in the evening after work, I noticed one had a bit of flaky scaly skin on the back of the neck and shoulders. Today, it looks a lot more scaly and is more around and between the ears and a bit on the back and sides.    Another baby has a little tiny bit on its side, but it does not appear to bother them. I don't think it's somthing stuck to them, because I tried to wipe it off.They are overall pretty healthy looking and active. They live indoors, and the mother's skin  is fine.
Is this due to the dryness of the air (it's winter here and we have the heater's on) or does this happen when there fur begins growing, or is this something to be concerned about?
Thanks!


Answer
Nothing to really be concerned about. IT is them shedding their thin layer of skin as a thicker fur bering skin comes in. It is  kinda like dry scalp on people that only last for about a week. All of the babies will develop it, and it will go away completely once all hair is grown in. It could also be a bit of urine and milk too. But nothing to really be concerned about.
