An unhappy bunny is one who is lethargic, doesn't play or interact, doesn't chin things, don't hop around and explore, is not inquisitive..
Grunting can mean any number of things. My bunny talks to me, she grunts when I pet her and when I give her treats. She also grunts when she's in a bad mood or I move her cardboard hut.
Another bunny can mean a lot of extra work for you in the sense that you're bunny Binoo may not be interested in you anymore. They will be each other's friends. Have him neutered to eliminate spraying and stink. If you want to try another bunny, ask a rescue to foster one. And research bonding tips since you cannot expect Binoo to just be okay with another bunny coming into his room.
