Great looking herd of rabbits.
Your son is pure happiness holding that bunny. Congrats on your wonderful beginning!
On a whim I put a wiffle ball in our does hutch and boy, she really flings it around and plays with it. I also throw in apple and mulberry branches for them to chew. Some of the rabbits rearrange them, drag them around, others just chew. They are quite amusing to watch, have fun with yours!
