Congratulations in getting your own bunny!
There are adorable at this stage. I bought mine few years ago. It's a fluffy lion head rabbit!
At the beginning, I feed it about 2 spoonful in the morning before leaving work and another 1 spoonful in the evening. I think it is constantly hungry and ready to eat more pellets, so there is no need to over feed the bunny. In the evening, I will feed it extra snacks while playing with her.
Hope your bunny grows up strong and healthy!
