Welcome to the forum! They sound lovely, and that’s great that you wanted her to have a friend.
As you are new, I just want to mention that once the girls hit puberty they will need to be separated, as they will likely start fighting. Female rabbits also have a very high rate of reproductive cancer if they aren’t spayed (around 60-75% by age 4). Most vets spay females at around 6-9 months of age. Once they are spayed and healed, and hormones have settled, you can go through the “bonding” process with them to ensure a happy relationship if you want them to live in the same enclosure.
Not trying to overwhelm or sound lecturing! We do have lots of people come on the forum seeking help because their bunnies suddenly started fighting after living together as babies, so I just wanted to give you the info before that happens!
