Do the carnivores still kill everything even when they aren't hungry?
I actually stopped playing this due to this bug/feature. Are you able to make an ecosystem within a single pen now?

They dont kill as often as they used to. Though I dont recomend making a pack of raptors since they seem to kill more than my big carnivores.

Yeah, it's not so bad as before the update. The more carnivores you have, the more herbivores will be killed (which makes sense). One big predator kills less than a pack of raptors.

If you want to make a pseudo ecosystem I would suggest only putting one big carnivore in a pen with multiple herbivores (if you don't want to keep replenishing your dinosaurs all the time and only do this if you have money to burn).

I would also suggest if you do want to use small carnivores, only to match them with either armored herbivores or sauropods. That works really well as the small carnivores will square off against the armored herbivores, but won't kill them. Also none of the armored herbivores will panic, so that's also a plus with this combination.

When the 1.8 update is released, you can even easily mix medium and large carnivores with sauropods (without them being panicked all the time).

I originally had put several triceratops in with a couple ceratasaurus. The cera's would kill all the triceratops even though their hunger meters were full as I kept them fed to avoid this very issue. I could deal with one here and there for sport/fun, but just going from one to the next was too much. I hate to use them term realistic with a game like this, but if it's going to attept to simulate life it needs to not have them just be constant killing machines just because they can.

With the current version of the game, the Ceratosaurs will only kill when their hunger meter is almost in the red zone (and won't go psycho anymore).

If you have two of them together in a pen with say 5 Triceratops, each Ceratosaur will kill one Triceratops when hungry. So that means you lose 2 Triceratops each time when they decide to go for a kill (or lose a Ceratosaurus if the Triceratops is stronger). That can become really expensive as you need to keep hatching and releasing.

In that case I would suggest the following combinations;

Either mix the Ceratosaurs with sauropods or use small carnivores like Velociraptor to mix with Triceratops. Both work and you won't have to need to replenish dinosaurs.

Yes they will kill even if there are goats/plenty of meat feeders. Worse yet the herbivores will often get stuck in a state of panic and refuse to eat/drink and die that way as a result from the stress.

What we need is a instant replacement option for dead dinosaurs - so when one dies it is replenished at the hatchery or via some other means.

So this answer is a complete contrary to the previous answer. Both can't be correct.

No, both are right - they only hunt when hungry, but they prefer hunting over feeders.

Anyway, I don't see why anybody would want to keep prey animals in the same pen as their predators - makes no sense from a zoo management perspective...

Yes, carnivores will act and hunt always in following way (each one is more prefered by the other and if one of them is not available the next one in line takes precedence);

humans > dinosaurs > goats > feeders

Although I'm not sure if humans fill the hunger bar... have to test that out (unless someone knows). I do know carnivores love killing them.

The point would be to create a self sustaining ecosystem. Using a cheaper herbivore to feed the carnivores when they're hungry, but just having them roam free when not without threat of being killed just because they can be.

That makes no sense at all. Your dinosaurs are all female and don't reproduce on their own. Whether a carnivore kills only when he is hungry or not, it's not possible to create a self sustaining ecosystem since the herbivores (and carnivores) will just die out from either being eaten or dying of old age.

not everyone wants to play the game exactly the way the movie dictates - some people just want to play with dinosaurs.

I have a T-Rex with a bunch of Gallimimus on Sorna. I need to replenish the Gallimimus population every half hour. So yeah, they still kill but they don't kill like psychopaths.

I would obviously have to replace the ones that die. It makes perfect sense.

I don't think you understand what self sustaining means. It's not self sustaining if you need to replace one species every time because it gets eaten by larger predators. Self sustaining means that it's balanced and doesn't need any interference from you. It's not possible to create a self sustaining ecosystem in JWE, since dinosaurs don't reproduce on their own.

Ok, stop arguing with me about how I want to play the game. I wanted to know if the carnivores will still everything even when they're full. What I want to do past that is none of your business. Have a good day.
