I killed the hag and found her staff, then I rested and Gale wanted to eat it.
I gave it to him but it was very annoying.
I think I will try to drop some magic items on the ground before resting, lets see if that can avoid the issue.
Once he told you he needs to eat magic items the quest log will have a list of what items he wants ( out of those you already found ).
There will be some items where I have no problem losing them, but some of them I want to keep.
