Egg Spawn Chance

I hit lv 20 yesterday and still have not gotten a 10km egg, I with a group of 5 friends last night and all of them had gotten a 10km egg, one friend (who was only lv 8) got his first that night as well, and i have constantly had eggs hatching, I will always have eggs in incubators and i usually have around 2-6 incubators, also with a total of around 75km traveled, so its safe to say ive have gotten a lot of them, but i still have not found a 10km egg, I also get more 5km eggs than 2km, around 2x more. I cant find a page with the spawn chances of the eggs, can anyone pull these and post them? Very interested in the data.
