My rabbits are 4.5yrs. While I have made a pen for them to move around, notice that only caome to pen to eat in day time. The orange female is very wary of her surrounding and will vote back to the cage all the time. The grey female mostly spends lying down. How to make them love around? I only had them for the past 3 weeks and so far the have allowed me to pet, brush and occasional carry. They eat from my hand and beg for food.
