I have had my baby yellowfoot for almost a week now. When I checked it yesterday I noticed that the dark area on its plastron seemed larger and that it was not entirely hard. It was somewhat soft (which I assume is normal) but it almost feels like moist cardboard when I press on it. I'm worried that it may be rot or something like that. I only spray its container once a day which tends to keep the humidity about 45% on the hot side and 70% on the cooler side. Temp is always above 80, even at night. And I feed it a spring mix with a little bit of calcium powder. It has been raining here the past few days so it has only been outside twice and I also soak it once a day. After looking at the shell I am considering taking it to the vet, but I'm curious to know what you guys think about it...
