Yeah, someone said that getting chickens to lay iron bars crashed the game, but we can't be sure how he tried to implement that, either.
Added some more stuff to the OP based partly on what you said.
These results have pretty clear implications for anyone trying to make exotic eggs. For instance, if you made eggs with normal shells filled with super-valuable god-chocolate, the properties and value of that filling will almost certainly not matter. Seems like nothing matters except the shells, as far as I can tell. This is a little disappointing, as it limits what we can do here. Enjoy your eggshell-munching!
What if you set a creature's eggshells to be made of gold, but have edible yolk/white? Would you end up with eggs that could either be cooked or melted down?
You've got to be careful with eggs...
Is it possible to create a reaction that makes an egg? And if so, could you hatch it, either where you made it or elsewhere?
EDIT I've read that it's possible to make ane "egg" so far, but it's not a creature egg. Looks like there's still some ways to go for my plans.

Note that it produces a dwarf egg! The bad news, however, is that the game doesn't notice that the egg box already contains eggs when it is constructed. So these probably won't hatch. A test is ongoing.It could also be that the mother is required to be married for the eggs to actually hatch.This would actually make sense from a biological point of view. Chickens and many other egg-layers can still lay unfertilized, sterile eggs even if they haven't mated. A sentient egg-layer might find themselves having to lay sterile eggs periodically, even though they're not married or having children yet. I have no idea if that's what's actually going on in the DF code, someone needs to embark with an egg-laying race and let some of them get married.
I have a married couple in my fortress, I'll see if I can get the wife to claim a nest too.
The only problem I'm getting is that the goblins are due to show up any time, and I so far have no defenses to speak of.

It appears that if you include a LAYS_UNUSUAL_EGGS tag it crashes DF. I tried it with a longsword, and someone else on the boards tried it with metal bars.
Also, it seems reaction-created eggs don't hatch :(.
You shouldn't need that tag to lay golden eggs, if that's what you're doing. You can specify any material for egg shell, whites, or yolks.
Unless you want it to lay gold bars or something, of course.

I am using it right now to make Golden Geese. However none of them have laid eggs yet. Instead a WILD turkey came in and laid eggs!!!

Someone suggested they weren't meltable so I decided to try for plain gold ore. Still waiting. Still surprised that a wild animal would come in and give me free eggs ;D
That doesn't look like an item token to me. I think the token for stones is "STONE", and you'd need to use the native gold material if you want to be able to turn it into bars like you would actual native gold rocks.

Exactly correct. I like to think of it as the avian equivalent of getting one's period...
It is and it isn't. Obviously, chickens don't menstruate and have nothing analogous to that at all, but they're both at least related to ovulation, which you just don't really notice (per se) in people because we don't lay big honkin' eggs.
Of course, that doesn't stop PETA from saying "EGGS ARE CHICKEN PERIODS!!" in all caps on their children's sites, but hey, who says political propaganda has to be grounded in reality?

Both phenomena consist of a female's body discarding an unused ovum. The only difference is what comes out with it. Blood and uterine tissue in the case of humans, or eggshell and amnion (and some membranes) in the case of chickens...

The problem here is that "what comes out of it" is what's actually being discussed, and there is no physical relation at all between a chicken egg and, well, anything that comes out of a mammalian female during menstruation (except maybe the egg cell, which isn't what they're talking about and isn't even visible).
Also: Chickens lay eggs to use them. They're not being "discarded".

IIRC the yolk is technically considered to be a highly specialized organelle of the egg cell, so in the chiocken's case the cell is visible once you cut away the shell, membranes, and amnion...
If there's a male human who also isn't part of the civ on the map, you may have a chance.looks like I have to abandon and add some type of Pet tag so I can buy a human or wait until a Human caravan comes and impregnates her. wait I do have DEAD Humans will they knock her up?
Otherwise yeah, throwing weapon.
SUCCESS!!!!!

The egg of the married dracon has hatched successfully and created a bouncing baby boy!
New Observations:
- Only eggs from MARRIED fortress members will hatch. All others are infertile.
- Although the egg claims to be the egg of a certain caste once hatched the caste is randomized normally.
- The hatched child gets mother and father information properly.
- It seems to take about half a year for an egg to hatch.
- The mother does not have to be present for the egg to hatch (the mother was sleeping in the barracks)
- The mother will collect and carry the baby around normally.

Perhaps we're witnessing the gestation cycle/period of a dwarf as an egg?
Sweet: the conversion rate from egg to child is one to one. Hard to predict when the mothers spawn eggs though.
"Decaplets have hatched."
This next question sounds so sexist but it's not, really. Does anyone know if a non intelligent female caste member will produce offspring if there are only intelligent male cast members around or will they never reproduce?
It will be interesting to see what people do with this new feature and I can finally get my antman queens laying eggs.well if past experiment taught me it is yeah intelligent creatures will spawn if another one of the same race is near but this was when they where tamed I don't know if two friendly characters will poop babies in your nest.
On the topic of civilised creatures laying eggs: do we know if the mother needs to have been married when she laid the egg for it to hatch? I can imagine a female laying many eggs, getting married, and suddenly having many, many, children hatch at once.

Solution: Fill your meeting zone with nest boxes.
That way when the giant Rocs and Cave Crocodiles turn up you'll know where they're going! :D
Bit of an update. The mother of 'the first ever hatched fortress resident' laid another egg shortly after collecting the hatching. This one however doesn't seem to be hatching. So there may be something I'm missing.
No. Nesting boxes are buildings. The wild animals using your nestboxes thing has been reported as a bug, so Toady may do something about it in the next release.what a bug? If I didn't want animals to go plop eggs I could just built it inside or made a hen house. poop I'm so close to figuring out how to breed adventures with out hacking with that feature.
Yea I haven't given up on her yet. And I actually managed to get lucky and get a good supply of adamantine so my military is decked out, despite the utter lack of any of the metals the embark said was here, so I'm in no real danger of losing the fortress to a siege anymore.
So far she's still the only mother to have successfully hatched a child. I had 2 other attempts, but I lost both of the other eggs to a combination of 'dwarven stupidity' and overseer oversight (needed a new food stockpile, forgot to forbid eggs...).
I moded gobbos to lay eggs...fun ensued and I caught several and gained some goblin eggs...since gobbos dont marry they cant quite spawn in your slave pits now unless you change them a tad.so any one seen a wild animal egg hatch in their nest yet? If so then removing the smart tags on your creatures might be the solution to get them breeding.

But if you could get invaders to lay eggs and hatch, you could make your own Goblin colony :P
wow when did Dwarfs go snatch the babies and children of Goblins?But if you could get invaders to lay eggs and hatch, you could make your own Goblin colony :P
or, even better, breed them for training purposes.
Hmm... I just had a thought...
Is it possible to have multiple types of eggs tied to one creature if we get the bug to do with unusual egg types fixed? We could have creatures laying regular eggs most of the time, with an occasional unusual egg.

I know that invaders are capable of becoming pregnant and giving birth on the map. If this is possible, it should also be possible to eventually cause some goblin eggs to hatch. For example, I recently read about an invading tiger woman giving birth to cubs while trapped in a murky pool over the course of several tigerman sieges. The problem is that the exact factors that lead to invaders becoming pregnant are unclear.

I thought that the conditions required them to appear on the map, with their beloved - which means that they had to be Named invaders from worldgen. Possibly they can show up pregnant, or their mate may also have to show up. I would be interested in data proving/disproving this. I have only had once pregnancy, they were named, but I did not have an easy way to check if they were married in worldgen.
COuld you add up a little question there?
Since eggs can hatch, how the hatching works?
Would it be possible to craft eggs that hatch things like Golems and such?
I'd like that...
If anyone hasn't tried yet (I don't remember seeing a post in this thread), I made an asexual egg layer pet with no [MALE] or [FEMALE] tags, but its eggs wouldn't hatch either. Unless the game defaults to one of those... although viewing the creature it did say 'it'.
Judging by people's responses here, egg fertilization occurs the same way impregnation in general works, so an asexual caste's eggs would never hatch.
I'm still curious about a male egg-laying caste, though.
I highly doubt that putting both [MALE] and [FEMALE] on the same caste would work at all to begin with, although people are welcome to try!I asked about that once in the Future of the Fortress thread. It will pick one of them - either the first tag or the last, I don't recall which.
