That first one may very well be a boy, i can't see his tail well enough on the pic to tell plus again, I'm a novice at this. Whoever had them both did decent job keeping them. They look nice! Are they nice and heavy?They were fairly sure one of them was male. I spent the morning reading stuff on the Internet trying to see if I can figure it out. Decided I would just leave it to the experts.
It probably doesn't really matter as they will mainly be kept apart.
I have less than zero desire to ever breed sulcata. I don't think the frozen waste lands of Michigan need more sulcata.
