My rabbits Lily and Blizzard live with lots of friends...five dogs, 8 turkeys, 30 chicken friends, 5 guineas, four horses, 2 cats, and countless cows. 😄
My rabbits had this same problem a couple years back...no need for a vet! There's a little tube of this medicine called "Terramycin" and it's available at most farm stores or even pharmacies. Just put a little bit in the corner of the eye daily.
