I have over the last twenty years become fairly successful in Breeding several different types of Reptiles including a few Turtle and Tortoise species. The Tortoise that gives me the most Struggle is the Russian Tortoise. I have Two Adult proven males and Four Large Adult Females. I'm to the point where each year I consistently obtain a Decent Number of Eggs, but no matter what I try, my Hatch rate is Pathetic! I don't have this problem with other Torts or Reptiles. Any Secret Tips? I live in Southern Calif. Thanks in Advance.
