This is the common practice that I adopt. A couple of days before I send my rabbits away, I give them a thorough physical examination to ensure that they are free from mite, wounds, diarrhea and malocclusion. This is to avoid any discrepancies.

So glad you do a physical exam on each bunny before they depart to their new homes. You are a Responsible breeder my friend! Cheers to you!!:-)
