We rescued our RF "Ruby" from a family who thought that she was a box turtle. Needless to say she was in poor condition when we picked her up. The one thing that we are not able to correct for some reason is her dry skin on her head and front legs. I have tried everything from daily spritzing in her enclosure, daily soaking, etc. She is in cypress mulch and she drinks a lot of water, nothing seems to work. Do you have any suggestions to correct this problem?
