Let me know when you find out how, I’ve been trying to pick mine up calmly for 5 years LOL.
But jokes aside, rabbits generally don’t like to be picked up as they feel like they are being taken by a predator. They can however be very loving overwise, I have cuddles with my boy every day and he’ll snuggle up to my leg… So you can definitely still have affection with a bun that doesn’t like to be held. Let us know if you need tips on how to get him used to pets and cuddles.
Otherwise, if you need to pick him up for handling purposes you can try approach his level, calmy pet him and scoop him up. Making sure to support his bum really well. If this still doesn’t work I’ve heard you can train them by slow touching their sides when you pet them, progressing to stoking their belly and progressing to having you hands around them without picking them up, letting them jump away when they want, its a slow process that could take months. I usually manage to pick mine up by being calm and petting him and putting my hands over his eyes and gently picking him up.. He will run away from me several times before but I just remaim calm and keep talking to him reassuringly and being on his level till he lets me get him after a couple minutes.
But some bunnies still refuse this and the only way to handle them is by using the towel trap to pick them up i.e, throw a little towel over them quickly so they are confused for a second and quickly scoop them up and move the towel off their heads.
Sometimes it can work better to make arrangements so you only need to handle them for nail clipping and vet trips.
