I feed my bps during shed and they do just fine with it but when i was first getting into snakes my mom bought me an albino hatchling cornsnake that was mid-shed and the pet store told her to make sure i feed him on tuesday sooooo tuesday rolls around and i feed him and he eats it and it sat in what i thought was his belly but was actually where his shed had stopped. i assumed he was fine and went to sleep. The next morning i woke up and had a dead snake so i guess it kinda differs from snake to snake and how far along in the shed they are
