Expert or not they're too young still. Could go either way still. But I have been somewhat right on some young ones I raised up. Pip looks female, vanilla bean boy, nisei girl, and Trex boy. Ttex appears to have either old or newly starting fungal on his femoral scutes too.
Thank you.
He had some pretty bad fungi on his plastron as a hatchling so his original growth tends to struggle with it off and on. Which is weird because none of my other 5 have ever had any.
Very likely you have both sexes represented but as previously stated they have some growing to do. Females grow into their tails or males grow large tails at this age!
Just a friendly FYI, for everyone, some people may be new members, but they may have had tortoises long then you. The join date of a forum doesn't mean that's when they got into tortoises.
