Hi Ktrab3296 – I am so sorry to hear that, and can understand your frustration and sadness.
It doesn’t sound like they had the best life before you adopted them… that means they are going to take longer than most to get over that – same as when you adopt any other abused animal… and for them, living in a small cage was horrible.
I will also suggest the same as Terra – Sit on the floor in the room with them and just IGNORE them. Read a book, play on your phone, watch a movie… let them come up and sniff at you (may take a few times) but don’t react and don’t even try to pet them yet.
Then slowly start having food for them with you… start by putting it on the ground closer to you and work at getting it closer and closer…
Please know that its not you – they are just scared. Even when a bunny lunges or tries to bite, its because they are scared.
It’s just going to take time and lots and lots of patience.
And at the end of the day, just know, you are giving them a WAY better life then they would have had with out! So good job!
