My 5yr old male Great Basin has been breeding with his mate and I had not peeked in on him for 2 days.But today when I checked on them I noticed that one of his hemi penises is still out and it is turning dark almost black and dying out.Has anyone ever had this happen and should I be concerned or will it just die and fall off.This is only his second year at breeding and he is more of a personal pet than a breeder.Any help would be appreciated.Thanks,John
