My barn is not that big, I have one 6 stack and one 3 stack cage, a giant food tub, 2 air conditioners, and one extra big cage. I have space issues, 3 of my rabbits live outside due to the lack of space. I cant just get a new barn right now, any way that you guys think that would help to make space? I was thinking adding another outside play pen so that 4 bunnies could run around but then I thought that does not really help...
