You built a feeder. It is sitting there. The animals ignore it, nothing registers as satisfied, and the game gives you no error message. This was reported on the official Steam discussion board in a thread titled *"Feeder not registering"*, which drew several replies — so if this is happening to you, you are not alone and it is very unlikely to be a broken save.
Work through these in order
- Confirm you built the right feeder type. This is the number one cause. A herbivore feeder does not satisfy a carnivore and vice versa. Diet is the requirement BioEden communicates least clearly — check the species' entry in the Bestiary under “Animal and Plant Required” before assuming the building is faulty.
- Check the range. The feeder must be within the area the animal actually occupies. A feeder at the opposite end of a large dome from a species that stays in one corner is functionally absent. Move it closer and watch.
- Check power and water separately. BioEden runs two independent networks. A building can be fully powered and have no water reaching it, and it will sit inert either way. Trace the cable and the pipe individually rather than assuming adjacency means connection. See power and water.
- Check network capacity. Placing one more building can push an entire branch below the line. If several things stopped working at once, this is why.
- Confirm the animal is actually a resident. An animal at Biome stage that has not reached Residency behaves differently from a settled one. Check the Residency tab in the Bestiary. See residency requirements.
- Give it time. Animals do not teleport to a newly placed feeder. Let a few in-game hours pass before concluding it does not work.
- Recycle and replace. Only after the above. Recycling gives a full material refund, so this costs nothing but time, and it clears any genuine placement state issue.
The most common single mistake
Placing the feeder after the carnivore rather than before it. By the time you notice your herbivore population dropping and go looking for a solution, damage is already done. The correct sequence for a mixed dome is:
- Build and supply the feeder
- Confirm it is powered, watered and in range
- *Then* introduce the carnivore
Doing it in this order avoids the entire class of problem. See carnivores vs herbivores.
Is it actually a bug?
Probably not. Of everything reported as "the feeder does not work", the overwhelming majority resolves to one of four things:
| Reported as | Actually |
|---|---|
| Feeder is broken | Wrong feeder type for that animal's diet |
| Feeder does nothing | Out of the range the animal occupies |
| Feeder shows no effect | Not connected to power, water, or both |
| Animals still hunting | Animal has not reached Residency, or the feeder was placed too late |
That is not to dismiss the possibility of a genuine bug — BioEden is a launch-window release from a small studio. But check all four before you report one.
Cannot find the feeder in the first place?
That is the other half of this problem and it has its own page. The Carnivore Feeder is an interior building filed under animal care, not under food or production, which is why players searching the production categories conclude it does not exist. See where to find the Carnivore Feeder.
If it really is broken
Post on the official Steam board with the species involved, which feeder type you placed, a screenshot showing the feeder and the animal in the same frame, and confirmation that both networks reach it. That level of detail is what turns a report into a fix.
Frequently asked questions
Why is my BioEden feeder not registering?
Most often the wrong feeder type for that species' diet. After that: out of range, not connected to power or water, or the animal has not reached Residency yet.
Does the feeder need power and water in BioEden?
BioEden runs power and water as two separate networks and buildings need whichever they consume. Trace the cable and the pipe individually — adjacency is not connection.
How long before animals use a new feeder?
Give it a few in-game hours. Animals do not teleport to a newly placed building.
Should I place the feeder before or after adding a carnivore?
Before, always. Placing it after you notice your herbivores disappearing means the damage is already done.
How this BioEden page was verified
BioEden Wiki & Guide is an independent fan resource, not an official one. The the problems documented on this page were reported by real players on the official BioEden Steam discussion board; system behaviour is cross-checked against official screenshots. Where BioEden has not published a value, this page says so instead of guessing, because a wrong number in a BioEden guide costs a reader a dome rather than merely being untidy.
