The first YF I got was a rescued full grown female in '04. Then I was given a male in trade for a gulf coast box turtle in '06. He looked to be a juvenile, but I think he's just a smallish specimen. I hatched out 3 YF eggs in 11/06, and this was before I knew how important humidity/moisture was for smooth shell growth. So they look like little pine cones. Then in '09 a young expectant mother-to-be brought me a young female YF up from Los Angeles. She was afraid she shouldn't be in contact with tortoises with her soon to be new baby. In the pictures, the male is on the left, the full grown female on next to him going towards the right, the rescued young female next to her then one of the pine cones.
