Hi!
I got my bunnies when they were between 7 – 8 weeks old and have been with me for three weeks.
I let them in their cage for 1 day. I did have to open it up to clean the poops so I had to stick my hands in there. On the second day I opened the cage for them to come out and sniffle. They didn’t come out immediately. I sat down by the cage a lot. On the third day they were out binkying and I started hand feeding them pellets. That has really helped with the bonding.
Before that Arya was just sitting in the corner most of the time, seemingly scared. But from the moment she was allowed out she has really changed and is now the first one to come to me.
So my advice, open the cage and let her come to you on her terms. I don’t know what your setup is but a small room with not a lot of distractions might be best.
I had the bunnies for two weeks before I went to the vet. They needed their yearly shots. In two weeks time you can already bond really well!
Hope this helps!
