Not a garter but a colubrid

I know nothing about this to help but sure hope you get some answers that do. Any chance you would share some pics of mom and the eggs? If you can find a way to incubate them to term what are your plans for them? Release or find homes? Does this change your thoughts on what your doing with mom or did you already release her! Cool surprise.

in perlite or vermiculite in a tub in your reptile room sounds good to me. thats how i used to do turtle eggs found in the same climate
