Ya i would say about a week also, giving them baths speeds it up a bit, my bd has shedded 2time in a month, well 1 1/2 lol he still has his body to shed, hes only done the tail 2 times so far
Honestly, it depends on what kind of shed. A shed of an arm or leg takes about a week. A full body shed could take awhile, though, if it's going arm by arm to tail to leg to head....
Definately depends on the age of your beardie and the area they are shedding.
When they're young they usually power through their sheds!
My juvie took a week to shed his belly, 3 weeks to shed his neck, 2 weeks to shed his head and Im on week 2 of his arm shedding ^_^
