Exotics need to be tamed. Tigers, jaguars and the like are also exotic and breed normally once tamed.

Right. You jogged my memory about why I changed the [PET_EXOTIC] to [PET] tag in the first place (this was last summer).

As I mentioned, I could not get the draltha to breed, so I just caught more draltha to replace the dead ones over time.

I added the [PET] to "cheat," since I did not bother to feed the draltha once caught. Taming them would force me to feed them. If you keep them "wild" the are fed by magic. Hence, why they died of old age and not starvation.

A side effect of adding the [PET] caused massive births.

[Noobazzah]

I believe the same works with elephants? One could raise a herd of wild elephants and then selectively capture some of them for war animals until they die.

[_Ivan_]

Definetly will keep you guys updated.

I've added in the [PET] tag as suggested and so far nothing but it hasent been 3 seasons yet so there is time to wait and see. If this one dosen't hatch maybe it's because the egg is already dead or unuseable since it was layed without the tag. I'll have to dump it and let her lay again.

Aweful lot of work to get baby dragons but who ever expected dragon breeding to be easy?   

[Noobazzah]

As said above, the [PET] tag helps nothing. Even if the dragons are wild. Because then they wouldn't claim your nest box, they'd just buildingdestroy it.

[Garath]

Nope, the CHILD tag has always been enough for me.

My experience comes from breeding Draltha.
By default they have a [CHILD:5] tag.
They would not give birth.

dragons have [PET_EXOTIC], no need to add [PET] as well. Most likely, the trainer who reinforces the tameness of the dragon is upsetting the hatching. I've had this with a variety of creatures before, giant sparrows etc

Draltha have the [PET_EXOTIC] tag by default. The draltha would not give birth and would eventually die of old age. When I changed the tag to [PET] they popped out so many draltha babies I had to add draltha meat to the fortress menu.

I am not sure if this matters, but despite what the [PET] tag implies, I did not use any trainers and kept them as "wild" so to speak. I just caught them and set them free in an enclosed "farm."

@_Ivan_ I say it is worth a shot to add the [PET] tag. Let us know the results.

I hope you see the humor here. [PET_EXOTICS] breed, it's known and done and proven now. If they don't, something is wrong that is not in the raws. You've given us the answer too (though I'm going to try too) in that you don't tame them. Or maybe not using current version.



Now I'm going to repeat again: spend some time looking there. Does a trainer come in? does the trainer cause the female to move? does the trainer cause the female to crouch? This was the most common problem with me training exotic birds. The trainer giving reinforcement to the female would cause it to either move or crouch, which kills the eggs.

Exotics need to be tamed. Tigers, jaguars and the like are also exotic and breed normally once tamed.

previous version (31.25): exotics didn't breed, period, so yes you had to remove exotics tags back then

Hmm.. Well, another clutch of 2 eggs and 6 months proved useless. I'll try removeing the pet_exotic after another season and see what happens. My legendary trainer isn't going in to retrain (as far as i've seen) so i'm 99% sure thats not disturbing the eggs.

Could be pure bad luck right? Not every egg is fertilised.

[Noobazzah]

Umm... Wait for a year? My dragons have [CHILD:10].That's all I've added, and usually after a year the eggs hatch.

[Sutremaine]

Maybe it's some specific egg bug? I modded jabberers to give live birth in the process of trying something else, and with no other changes made to the jabberer they did so. The eggs haven't been doing anything, though the changes I made elsewhere can't be absolutely ruled out. (I modded some other creature to give off gas that transforms a jabberer of any caste into a male jabberer, since I didn't catch a breeding pair and the caverns aren't producing any creatures any more.)

[GreatWyrmGold]

If it makes you feel better, many species of modern reptiles as well as perhaps many archaic archosaurs, notably some of the larger herbivrous saurosuchans, were viviparous.

[_Ivan_]

Well, tried removing [MEGABEAST] tag and no luck.... Read that it stops hatching.

Added:    [CHILD:2][GENERAL_CHILD_NAME:dragon hatchling:dragon hatchlings]
   [BABY:1]
and hoping the BABY tag will kick things off. Also switched back to PET_EXOTIC since it seemed to have no effect as PET and it's been said several times that both will breed.

I've read everything i could find on the subject and i don't know whats stopping them from hatching. Her training isn't even budging from masterfully trained.

It's looking like this batch won't be hatching either. I'm out of ideas. Anyone having any luck?

[_Ivan_]

Well congratulate me. I now have a breeding pair of dragons AND hydras. The only problem is they won't breed. 

I've tried everything i could find on the subject. I even removed the [FANCIFUL] tag thinking it may be blocking egg fertilization. Still watching the animal trainer but they forget training very slowly so im very sure they aren't dieing. No trainer is assigned to the females and won't be unless they revert to semi-wild. BTW: dragons must have a very good memory because while the hydra lost 2 levels sitting on the nest, the dragon did not forget.

Another oddity is my hydra eggs do not show up on the kitchen list and dwarves will haul them if i don't forbid or lock the room.
This is what i've added to the hydra:
      [LAYS_EGGS]
         [EGG_MATERIAL:LOCAL_CREATURE_MAT:EGGSHELL:SOLID]
         [EGG_MATERIAL:LOCAL_CREATURE_MAT:EGG_WHITE:LIQUID]
         [EGG_MATERIAL:LOCAL_CREATURE_MAT:EGG_YOLK:LIQUID]
         [EGG_SIZE:6100]
         [CLUTCH_SIZE:1:3]
   [CHILD:1]
   [GENERAL_CHILD_NAME:hydra child:hydra children]

She lays but they don't hatch and the eggs get hauled.


Another sidenote, i think removing the [MEGABEAST] and [FANCIFUL] tags may have triggered an Age of Legends. I scumsaved since i believe it was due to the missing MEGABEASTs.

[Noobazzah]

Possibly, since a large population of megabeasts disappeared immediately, ushering in a new age. I have no idea what's wrong with your dragons, since I've had no trouble breeding them with the [CHILD:10] tag. Also, check if you've accidentally removed something while modding.

[Sutremaine]

Another oddity is my hydra eggs do not show up on the kitchen list and dwarves will haul them if i don't forbid or lock the room.

I've had this with VCCs, which have none of those messy megabeast tags. Are the eggs white?

Making them give live birth should work, but I haven't got around to testing that yet.

[_Ivan_]

Solved the missing hydra eggs in the kitchen list.

Added:   [BODY_DETAIL_PLAN:LEATHERY_EGG_MATERIALS] and (a new clutch must be layed) they will show up in the list.


@Noobazzah
I must be having incredibly bad luck. It's rare for a random set of numbers to come up the same 5 times in a row but it DOES happen. Any chance you were using cave dragons from the caverns and not the surface encounters? They are different raw entries so maybe...
