Usually kits do this to one another, but sometimes adults will do it to
if they hadn't had enough time to nurse from their moms. If the ferret
is young, it may grow out of it, but if the recipient's ear is getting
red and sore you need to do something. Continude ear sucking on the
recipient can cause cosmetic damage as well as infection. Try swabbing
some Bitter Apple or better yet Fooey on the recipients ears. This
should stop the ear sucking but if it doesn't, personally IMO, I would
seperate them.
