As others have stated what your seeing is normal behavior. Some bp's, not all but some won't eat during shed. Mine will eat but it takes him alot longer, usually he will have the mouse dead and going down his throat in mere seconds while not in shed, but while in shed it can take him up to 30 minutes to actually find and eat the mouse. I'm pretty sure they are also fairly shy while in shed so him staying in his hide all the time is also normal.
