Clicking noise in young rabbit joint

[pixielunafriends]

I recently got another rabbit, he is 4 or 5 months old english spot. We got him Friday August 16. Today when we let him out to run around the room, we heard a clicking sound, presumably coming from a joint. He has been out to run several times since we got him, and there was no clicking before. It sounds just like if a human knee, toe, or other joint would click. It is not causing him pain, as he is still running, jumping, and binkiing. Is this something to be concerned about? Should we take him to a vet? Any help is greatly appreciated!

(I got video of the clicking, but uploading it is not working)

Hard to know. I would at least keep an eye on it and see if it goes away or if he starts showing any signs of limping or pain.
