Hi would really appreciate everyone’s thoughts on my spur thighed tortoise. We thought she was female. But now not sure. She shows male behaviour towards my other female spur thighed (confirmed female by vet) and the tail is longer/ sits to the side compared to my female who has a short tail. She has also shown the sex organ many times but as we know females show sometimes too we are not sure. She is 8 years old. Her shell is hinged and slightly concaved. Any input would be appreciated. Thanks.
