My female desert tortoise Topaz has always layed two clutches of eggs per year. This year she layed one clutch with two eggs and then about a month ago she started digging around looking like she was going to dig a nest but never followed through with finishing it. 3 weeks went by and I started to worry. She stopped digging around and then today I found one egg above ground. She is about 25 years old and eating and active and generally looks healthy. She has a heated house on a thermostat and roams the back yard freely. She is fed Mazuri tortoise diet, dandelion greens, eats grass and hibiscus flowers etc...She is soaked in warm water every two weeks and drinks when we have the sprinkler on. I am worried she may have impacted eggs now. Need advice. My veterinarian retired, looking for another one currently. Attached are photos of her previous eggs.
