Still don't give up - even 1 on 10 is better ten 1 on 0. Pleas keep us updated.OK I agree that the new red patches, especially those on the plastron, don't look good at all. I too fear you may lose this little one.
With just the pair on the upper shell it looked like a ramming injury, but the patches on the plastron indicate that sepsis is likely. I'm so sorry.
