8 weeks? seems young. hmmm im not sure though no experience in that department sorry

i got my chin and she wasn't fully grown, oh wait i think she was 8 weeks too! (2 months they told me) and i didn't have to do anything special.
the only thing i'd suggest is to make sure your room and cage are CHINPROOFED the point of paranoia, i know that seems extreme but with playtime they will get into places you will be SHOCKED lol and also my chin broke her leg in her cage :| took like 3 months to fully heal and a few thousand bucks to fix....make sure there aren't any wide openings/holes etc. that she/he can get their foot stuck in (like, those ferret cages that have an edge on the side of the ledges for attaching ladders that come with them...what i had and what caused the leg break eventually

)
hope that helps
