Technically was a Chekhov’s Gun. They were told it was important and not to touch it, so you knew something was going to happen to it, and it did.  
People got greedy expecting hidden depth. If this fan theory was confirmed or jossed, it would be an extra treat, not long-awaited closure.

@Jarkes  
Its an unusual rock.

2 years later and I still don’t get why people made such a big deal about this or thought that it was a Chekhov’s Gun.

So what was the point of this thing?

>holder found a dragon’s nest  
>built the farm around it  
>no dragons anywhere  
>and this boulder was in it
 
some eggs are duds. how many centuries would it take for dragons to abandon their nest?

@patec  
Erosion or something, who knows. It’s not that complicated a shape.
 
 
@Masem  
Kind of randomish, but I’d headcanon that.

Just a random though:
 
Remember Rarity’s cutie mark story? Her finding gems in a rock? And that gems are seemingly organically grown…
 
What if in Equestria dragons lay unfertilized eggs which become rocks with gems inside (akin to how we have chicken eggs as food for us).

@Millennial Dan  
Then why is it egg shaped? And was coincidentally discovered in a nest?
 
For me it’s still a possible egg.  
But, as I said before, there is no point arguing in absolutes. Maybe the show will pick it up again one day, maybe not.
 
@ColdhardSilver  
to A: Well apparently (some?) eggs need some sort of “magical ignition” to hatch (see Spike), what if this one just never got one?  
to B and C: Sure, but if you’re told from the very beginning that it’s a rock, why would you look closer at it? Maybe Maud just never took a very close look at it, always just assuming her parents and grand parents were right.
 
You see, you can still argue both ways.  
But as I said before, there is not really a point.
 
(It could also be a fossilized egg. That way it would kinda be both, a rock, and a egg.  
Maybe that will make people in here happy…)

@Background Pony #4D70  
Ponies don’t not much about dragons, but they do know their geology. Not to mention that  
A) Such a stone as been with the Pies for around 10 generations  
B) The farm is manned with people who’s expertise and profession revolves around rocks  
C) Maud’s currently getting a college education centered around rocks and has already shown to be quite knowledgeable given the train station scene.
 
So both the rock and the egg theory have a stable basis.

@Background Pony #4D70  
What are you babbling about? We’ve seen a dragon egg before, and it looks nothing like that. Holder’s Boulder really is just a rock. Settle down.

@ColdhardSilver
 
Granny Smith AS FAR SHE KNOWS, which is ONLY WHAT SHE WAS TOLD. Basically, ponies know next to zero about dragons, and everyone has been told it’s just a rock, so of course they’re going to say it’s a rock. If you say a diamond, and were told it was glass, you would call it glass when you explain what it is to others.

If you don’t walk with it in your party, eggs wont hatch. And since it’s a Dragon type, it’ll probably take even longer to hatch.

@ColdhardSilver  

In case anyone was still confused, this.

@Blissey1
 
The quarry most likely was the nest, hens won’t always lay on an egg if they have too many at one time, and will sometimes even push an egg or two out if the nest is too cluttered

@ColdhardSilver  
well then the only conclusion we can come to is that dragons make nests on the ground out in the open
 
unless that giant pit/quarry next to the boulder was the dragon nest

@Blissey1  
She said:  
Granny Smith: “Well, now their great-great-great-great-great-great-grandfather Holder Cobblestone – he found that boulder in a dragon’s nest, older than time itself! He built the family farm around it, even though it was just an ordinary rock. It always brought them good luck.”

@ColdhardSilver  
You sure? cause it was found in a dragon’s nest, and their farm doesn’t look like it was built in a dragon’s nest.
 
going back and actually watching it, Granny does say something between “found in a dragon’s nest” and built the farm around it”, but I can’t quite understand what she says.

@Background Pony #A5D3  
He didn’t.  
Granny Smith said that Holder Cobblestone built his rock farm around the boulder.

How did Holder move the thing?

@patec  

 
Maybe it just means that old Holder Pie was the Bilbo Baggins of his day.  

 
We all do, son. We all do. :)

@patec  
because dragons are still a severely underdeveloped aspect of the setting
 
so this was a freakin huge tease.
 
and personally, I agree with you @patec. just wait till the season finale!

Why is everyone so worked up about this..  
maybe it is, maybe it isn’t.  
amaybe we will find out, maybe not.  
What does it matter? Just sit and wait. Jeez.. children..

@patec  
It means that a dragon wanted it there. That doesn’t mean that it’s an egg.

@patec  
Maud’s basically part rock, there’s no way she wouldn’t know something’s up. Quit being wrong.

@Tetrominon  
sure.  
But they found it in a dragon nest. That’s what Granny Smith read in that book.  
That detail HAS to mean something.  
I don’t know.. maybe I just want to see the Pie family again in the future :P
