rabbit house

Hi Everyone, i have 3 bunnies outside in Hutch. What can i use for beding on the run? Thank you and God Bless :)

I am in the process of researching rabbit raising and was wondering if this will work for maybe 2 or 3 rabbits with a few modifications? It was originally an a-frame coop and could be winterized more of course. Also any tips or pointers would be appreciated. Thanks!
