My rabbit likes to lye really weirdly. She watches tv (does your rabbit do that?). She is really crazy. Will you send some pics of the crazy stuff your rabbit does?
My rabbit was doing that and the vet said she has an eye infection but in your case it mite be an ear infection. They will give you some medicine and probably an injection. My rabbit is 2 and 1 half years old. That infection is the first illness she has ever had. (She is going through it now)
