@wyandotte102 - How sweet of you to rescue the little fella. I do highly suggest as others have mentioned to get him seen by a vet first thing and get an examination done to check basic health/look for parasites/maybe can help get him cleaned up and nails trimmed. They can have a look at that ear for you too. It may require some calling around, just ask their receptionist if they will perform exams on bunnies!
