I have 1 female rabbit who is about 3 months old and was lonely and yesterday when I got my 2 guinea pigs I put them in with her and they liked each other. They became good friends already. Is this bad for the piggies or the bunny? Also, I feed my rabbit fresh greens, and ground corn(my grandma gave me this tip) Can I put the guinea pig food in there for the guinea pigs to eat? I'm sure the bunny will eat it. Is it bad for her?
