i had the same thing happening to my baby a few days ago. He seemed perfectly normal and ate well. acutally moved up to adult mice instead of hoppers. After 48 hours i was handling him and found that the pink had gone away. it was about 5-7 days. now his head is starting to shed. how long has the pink been there? i was worried it was scale rot also, just watch ur humidity and temps and hopefully it isnt scale rot, but by the sound of it, it sounds like hes getting ready to go into shed.
