Sorry for not answering on your question before. And great that you are making process with your bunnies.
You should never force a bunny to be picked up, only when it’s necessary. You should slowly teach the bunnies to get used with being handled.
My steps of training the bunnies to be picked up:
1. Get used with being touched everywhere, they don’t need to be still but should come back and accept getting a soft pat. They should not be scared when you touch them.
I know some bunnies have a hard time being still and would rather run around. But you can do this while they are eating or when they are not active and up for play time.
2. Get used with just the front body lifted up while the back legs still standing on the ground.
3. Lifting them up a little bit off the ground or let jump up onto your knees and lift them up. You should be near the ground. Before you lift give a treat and also when lifted a bit of treat. Teach them to be calm in your arms and slowly in crease the hight.
You should encourage and give reward when the bunny are still and calm. Some bunnies love food other just love a bit of cuddle.
Use the daily pellets as a treat and it will be easier.
My bunny Toste when being picked up will just hold his food in the mouth if I cuddle him. I can also lay food in front of him and he won’t take it until cuddle time is over, so he loves cuddles more than food. That’s a surprise for me because he had a huge distrust towards humans and would always attack me the first year he lived with me and I have had him for 1,5 year.
Until you have trained your bunnies to trust you and doing picking up training. I would never pick up my bunnies. I will just find other ways. Using a travel cage, teach them to go their cages when it’s time and so on. Only when I have to pick up I will force them to be picked up.
For example Toste I have just started to pick him up this summer before I avoided to do it. He’s the most calmest of my bunnies when being handled and he often close his eyes and love being cuddled.
Hope everything goes well
