Hmm :scratchchin: that is interesting! I have seen my 4 ferrets love on each other, licking each other and what looks like even often nibbling on each other. I believe this is just a show of affection. Have you tried bathing Crunch, maybe there is a "momma" scent lingering? How old are your babies?
I guess in my honest opinion if no damage is being cause and it isn't stressing Crunch out then leave them be. They may be just adjusting to each other. How long have they been together now?
Oh... & welcome to PT btw!
