They are still very young and -- contrary to popular belief -- early handling does not make a rabbit easier to handle when older. They will each have their own tolerance of handling that probably won't be seen until after hormones kick in and they become adults. Some young rabbits will have a drastic change in their personality with the onset of hormones.
Here is a quote from Rabbits USA magazine:
Founder of Bunny Bunch rescue, Caroline Charland, states, "People often think a rabbit must be held a lot as a baby in order to like being held as an adult.I don't find this true at all. Over the years, the Bunny Bunch rescue I founded has saved many mother and baby rabbits from shelters. All the babies were treated the same. When they became adults their personalities varied-- some liked to be held, some hated to be held and some tolerated being held.
On a similar note, the two that you have may appear to be bonded, but baby bonds don't count. If you are housing these two together, there could come a time (again with the onset of hormones -- the age at which that comes can vary as can the extent of the effect of those hormones) when the two rabbits begin to have scuffles or even fights. Such fights can turn quite serious. So it is usually advised to separate hormonal rabbits if/when they begin to show signs of not getting along. Once neutered and healed, they can be re-introduced and possibly bonded (if the rabbits are willing).
