For babies under 6 months- nromally completed in about a day or two. though tiny flecks can still be left.
juvis 6 months to 1 year- 2-3 days. again small flecks. at this point, they may not do a full body shed.
adults- weeks. may shed a body part at a time, meaning tail here, foot there, casque another time.. can seem like they are always in a state of shed.
