Young bunnies are more interested in exploring. PLUS, he’s new, so as a prey animal, his instincts are telling him to know every crook and cranny of your home. Prey animals rely on knowing the best escape routes and hidouts. So that’s his first priority – feeling safe by knowing his environment.
But also note – most bunnies do not like to held. It is good to get your bunny used to being held, but for now since he’s so new, just gain his trust. If you force holding him everytime you see him, he may shy away from you. (I’m not saying you do that, but just in case you hold him the first time you see him, you may want to back off on that)
Right now though since you will want to littertrain him, you may not want to give him too much freedom too fast, so hang out with him in one room – bring stuff you can do on the floor, and just hang out with him without focusing on him. Let him come to you and give him a healthy treat or even just some of his pellets (since he’s so young, you don’t want to give him sweets, fruit or veggies) Alfalfa cakes are a good treat for young bunnies. Anyway, try that for a while. He may jump on you, and just let that happen without reaching out for him right away. Let him get comfortable with you just hanging out first. He may then settle down and lie next to you, then reach to pet him.
Keep us updated on how that works for ya!
