I appreciate all of your answers, but I would please like a little more credit.
I have all of them neutered and spayed except for Ginny because I got her under special circumstances and I forget the details but I was told that her original vet could not have her spayed for whatever reason. I have not tried to prove it for myself by bringing her to a vet, which looking back is probably now a good idea.
I did NOT just throw Hermione into the cage with the others, I did 6 months of research before I adopted my rabbits, I know better. I introduced them in a neutral territory and George and Fred are very fond of her now. Ginny has calmed down very much since I last posted and is now only biting or growling when she tries to lay down next to her, however, I did get them to share treats peaceably together. Ginny even started grooming her ears before remembering who it was, lol.
I’m sorry if I came off rather rude or arrogant in this post, I honestly don’t mean to and I didn’t realize how poorly worded my first one was. Thank you for your help and tips and I genuinely welcome any more anyone has to offer!
