Beardies shed every so often in sections. Never will they shed everything at the same time. When you see them shedding give them a bath or two a day, it really helps and they love it. What ever you do though, do not help them in anyway or form even if a good sized peice is hanging on by a hair thin peice. I can just say helping them with their sheds ((i imagine) feels like pulling off scabs to us. Once the skin underneath is fully ready the shed will come off( Unless the humidity was off)
Hope this helps- Matt
