Hi there! Yes thank you for taking these bunnies in. It’s great that your main concern is that you are giving them a good life!!
When trying to make this type of decision I would recommend evaluating what you believe someone else would be able to provide for these bunnies that you can’t.
With bunnies, as with most animals in general, we honestly have to make compromises on what we may want or expect from them. Many people want cuddly animals that can be held but most rabbits don’t fit that description. Is there something specifically you are trying to get them used to be held for? I pick up my rabbits but only when necessary. Some rabbits don’t allow this at all so a workaround would be to teach them to hop into a box or carrier when you need to transport them. Just because they don’t let you hold them doesn’t mean they aren’t happy. If they only let you pet them when they are eating I probably wouldn’t pet them at all for right now. Tolerating something doesn’t mean they enjoy it. With that said you may be able to work with them to get them to enjoy this type of contact. Some bunnies end up never liking being picked up or pet and it’s just something we have to respect.
I know you said you don’t know if they are happy because you can’t get close to them. Is there anything specific that makes you think they might not be happy? Since you have had them for two years is there something that has changed that makes you think this? You say they love the freedom so that sounds promising. I also wanted to clarify their living situation because you said they moved out of the hutch and into the backyard. Do you mean they have free roam of the yard and that is where they live 24×7?
