[200xth]

Would u know how long this process should take? Just so I don't chalk it up to him shedding then find out after its something else that I should have had checked out.

There's an excellent thread on the general BP forum regarding the entire shed process with pics.

Does a great job of walking you through the whole process so you know what's happening at each point and how long it lasts.
