Unlucky or normal?

YES YOU WILL!! don't give up. I'm at lvl 27 and hatched bunch of 10km eggs but almost all are eevees and non evolved to vaporeon. I had a badluck for eggs worse than you do haha but I got 3 snorlax 3 dragonite and 3 lapras all in the wild after a long wait so im pretty sure you will have one as well. I know mine is not that much because I have a friend that's got 11 snorlax haha it really depends. Or the best thing to do as of this time is to make use of what you have. I mean im sure you have exeggutor, poliwrath, arcanine, slowbro, and vaporeon right? they are surely a hell of a monsters =)

Lot of players cheat in this game.

They use 3th party sites to scan areas for rare pokemons and drive their cars and bicycles there for the catch.

Also they scan for areas which spawn dratinis and then they go get the dratini whenever it spawns.
Else they wont even bother to visit location unless it is dratini.

And not to even mention gps spoofers....jeez

Hang in there man. You're not alone in this at all.

For perspective, I have the following number of candies for these 10k mons (I've caught only a handful of each in the wild):
- Onix = 665
- Magmar = 567
- Electabuzz = 509
- Scyther = 354
- Jynx = 288

How many Snorlax's or Lapras' have I hatched? 0

-_-

I did get a Snorlax and 2 dratini one of which was 84iv, 706cp. Happy with those of course. But I'm 32 and no Lapras or Scyther or Magmar. 3 eevee's, 6 Onix and 8 Pinsir's and bunch of Kabuto's. you're going to get a lot of crap.

Seriously, out of three 10km eggs you got 1 new one, one good one that isn't up to your IV standards, and one shit one. STFU

I'm in the same boat, and I think a lot of others are too. I'm level 29, caught 4601 mon & hatched 390 eggs.
I have yet to hatch or even see in the wild a Snorlax, Lapras or Dratini. I hatched another 10 egg today, got a Pinsir :'( I have plenty tough mons but the top three elude me.

Hah! I've prolly spent $100 on incubators and hatched 714 eggs (not sure how many 10k but it's been a lot) I've hatched one Snorlax, one Dratini, and 0 Lapras. Conversely, one my sons has never spent a dollar on the game, has hatched around 4 10k eggs ever and has got both a Snorlax and a Lapras. I hope your luck is good because if you are frustrated now. Oh boy!

I think you need to re-evaluate your expectations. If you're really want to compare yourself to everyone else, then I have the perfect egg hatching chart for you.

According to the 2 different egg hatching charts I found that documented the probability of getting each pokemon from an egg using data gathered from players around the world, Hitmonlee actually has a lower chance of hatching than Lapras, Snorlax or Dratini at 2.6% to 3.3%. (Lapras: 4.3% to 4.5%, Snorlax: 4.6% to 5.1%, Dratini: 3.5% to 5.5%, Electabuzz: 7.4% to 8.7%)

What this means is that you've managed to hatch a pokemon that is so rare that statistically, a player would have to hatch about 38 eggs to get, in your 2nd egg. I don't see why anyone would complain, unless filling up their pokedex is not their main goal.

What you are really complaining about is that people in your neighbourhood are hatching Snorlax and Lapras easily, which you presumed to be true based on the fact that they have that pokemon in the gym. Now, I certainly don't know if you are located in an area where no rare pokemons ever spawn, and perhaps that's why you assumed that egg hatching is the only method to acquire one. But I'm pretty sure you haven't ask any of those players how they really came to acquire those rare pokemons. Unless you're actually playing the game 24/7 and actually do travel all over the town/city and are sure that there are no rare pokemons spawnpoints, I wouldn't be so quick to accept that conclusion.

I, myself, have never hatched any Snorlax before, and I only play the game within 5km of my home, but I managed to catch a Snorlax right in the middle of the streets, in the middle of the night. There were a group of people already there before I found the Snorlax on my sightings even though it was 3am, which isn't even a rare sight during the few weeks when the game launched in my country. However, I have never seen another Snorlax at night in my neighbourhood since then, even though my sister reported a few more appearance while I was asleep in the afternoon.

tl;dr
You're exaggerating. According to statistic, you're good with those egg hatchs. If your goal was only to get Lapras, Snorlax and Dratini with good ivs in 3 eggs hatched consecutively, then you're either over-estimating the probability of hatching those 3 pokemons, or you decided you're unlucky even without checking to see what's the percentage of players who hasn't managed to hatch those 3 pokemons is.

IMO, every pokemon has a different hatch rate

I've hatched over 800 eggs total and probably 80-100 10km eggs. Spent a lot of $$$ on incubators. And I've hatched only 3 Lapras and 3 snorlaxes. They are rare for a reason.

You hatched a dratini out of only 4 eggs. From a statistical standpoint, if Snorlax and Lapras are the only other desirable pokemon, consider yourself lucky.

I've hatched enough Jynxs to start a Jynx nightclub :)

i hatch 800egg, i got ONly 1 snorlaax PC507 (my 1st egg)
And 0000000000000000 Lapras!!!!!
