from what you're saying skunk is just being a normal girl. an older girl will fight back but the young ones just take it for the most part. its just normal working out of the hierarchy. after a while she'll stop pushing the others around. they're just getting used to eash other yet. getting her a larger older friend will be more difficult then just letting the babies run their course. as an older larger female will feel its her right to be queen as well as skunk thinking the same thing. the babies are just thinking, "ok, fine you can be queen, can you stop showing me that you want to be now??" it may be that matilda is a little less submissive and skunk has to show her more often that SHE is queen dang it.
