Assistance is sexing a pair of red foots

[MVPGH430]

Hello Everyone,
I’ve got two red foots that I would like some help sexing. The first picture is of my larger tort. The shell length is approximately 8 inches. The second picture is of my smaller tort, about 6 inches in shell length. They both look female to me, but the smaller tort might be too small to sex accurately. Any help is greatly appreciated. Thanks!

First one is female. Second one might be too small still.
