Rarity from eggs
So since a while i was wondering. Are some pokemon easier to hatch than others from the same egg type. For instance, i'm level 33 and never hatched a single Snorlax yet, while i hatched several of the crappy ones like Scyther, Jinx etch... i also have hatched an insane amount of 5km egg, never found a single porygon but like 30+ paras/staryu. Is there some data somewhere showing that something influences it ? Is there some different % of dropping? Or am i just being unlucky ? I know my sample might be little but am wondering since all the 20 or so people i do know that play this game have had pretty much the same issue. Or at least that's what they said.

I personally believe where you pick up the egg matters...more so for the mon probably than whether it's a 10 or 5km egg (just a higher chance of that mon possible).
I also think there is simply a lower percentage of some eggs so some mons are just simply more rare.
From my own hatches, 20% of my 10km eggs (excluding holiday baby 10km eggs picked up) were Lapras and about 13% were Chansey. I only pick up eggs from a few stops and try to only get eggs when I am about to spin one of these stops that I believe gave me a Lapras/Dratini or Chansey.
I have never hatched a Snorlax though.
Rather than pokestop relation, it could also be a Biome relation so perhaps a whole area are more likely to hatch certain things...like I have caught 7 other Chanseys around my area.
My wife/kids pick eggs from all stops wherever they are and haven't hatched any Lapras yet, but have hatched Chansey.
Same. I've hatched 8 chansey from the same museum stop.
No Kabuto after 1200 eggs, then a nest came and I got 3 in a week and a half.
Zero omanyte in area and I've never hatched one.
Snorlax are common here and hatched at least 6
Never hatched magnemite/voltorb/pikachu after 300 eggs from lake, switched to city square and immediately got them.
I could go on and on about eggs. I originally made an acct on this site to make a post about it months ago.
I do agree some pokestops are more likely to give you certain pokemons.
For example, I got identified one pokestop that almost always give me water pokemon (not comon in my area), and also I've got 2 of my Lapras and Snorlax frome there. The bad side is that is hard to get 10k from there.
If I pick up eggs randomly I usually ended up with Nidorans, Ponytas, Paras, etc.
It's really hard to say when your dealing with RNG. I went over 700 eggs without hatching a single Snorlax, then hatched 5 within my next 300, at 1124 now and still not a single Lapras. It's just dumb luck in my mind now.... People complain about Porygon, got 3, people complain about Chansey, got 4. I had theories, debunked most of them. If there is a true probability proven by someone who has collected a ton of data, I wouldn't argue, but I've came full circle to it's all dumb luck.
