Yes, the hob is the one on the right. The little runty girl is on the left, though she's growing very well and weighed 30 gm this morning. They'll start to look more like ferrets at around a month. It will take another 5 or 6 weeks to really look like you expect a ferret face to look.
That noise is why so many ferrets, even the early neuters, get so upset by squeaky toys.
