Thank you for explaining this. I haven't been able to find any information about location and movement of the follicles/eggs over time. I think it would be a great research project to take a whole bunch of snakes and watch and document the development of the follicles into eggs both through ultrasound and radiographs. It is one thing to hear people say, I think it is this or that, but it is another to have some evidence behind it. You and SquamishSerpents are helping me get a better understanding of the processThank you
