Many of the male Testudo will behave this way. It can increase in spring time too.
She’s a spur thighed
She probably isn't a she...
They need to be about 3-5 years before you can tell that way. My guess is you have a male hitting puberty.
They all look female wen they are juveniles. It takes years for the hormones to begin flowing and the secondary sexual characteristics to begin to show.
My tortoises are roughly late seventies to mid-eighties and both females and they've never done this.
It could well be a female. While it is more normal for aggression from a male, a few females also are aggressive.
Toward people, or other tortoises?
I've seen a few females that were highly aggressive toward other tortoises, but I haven't ever seen a female that was aggressive toward people. Have you? Please share the details. I'd love to hear it.
Personally I have a young female sulcata, maybe 40-50 pound range. She is human aggressive.
As for female Russians I recall chatting with a person in some tortoise group about the human aggressive one she had. That female was a large one who hated everyone, tortoise, human, canine
I want to say him and other torts. She would run at him and try to ram him even snapping at toes.
