Animal feed cost explosion

Just tried it - built 10 new storages and let the game run one year.

food costs decreased around 10k$, but that may be in tolerance.

So, i cant prove a relation between stores and increasing food stores.

Have tried it as well. Seen no impact.

Am running a Zoo for tests at the moment - 3 Species, 6 habitats total (1 habitat of each serves as control group for enrichment feeders).

Doing 10 years without enrichment feeders, and 10 with enrichment feeders in one set of habitats.

What I can say for now is that the price of food for one habitat can sometimes double randomly (without enrichment feeders). Also without enrichment feeders and without the surprise double billing, the price of food for a given habitat remains the same, even on the long term, as long as the population is stable. This brings an end to the "not consistent" part, at least without enrichment feeders.
Unless there is a bug, the price does not fluctuate at all. Otherwise, it will randomly double.

Am currently testing a set of enrichment feeders, will switch them out and test another, will report findings when done.

Did it "double" or did it just get fed twice as often in one year, because that is what I've seen. The feedings by the keepers just isn't consistent. Sometimes they will feed once a year, sometimes twice.

Good question, I am not sure. I have had this happen serveral times in the 20-year test, but I keep watching the same habitat (Lions1). Since the numbers have been extremely consistent apart from that* (Edit: Except some weird stuff with the Tortoise 1 habitat), I am inclined to believe that you are right about the keepers.

Which would mean that the issue with the "explosion" of prices is as follows:

1. Keepers not being consistent with feeding pattern
2. The Frozen Fruit Block, Pinata and Blood pumpkin contain grade 3 food no matter what the habitat food grade setting is.
3. The age of the animal does not impact the price of food. (Edit 3)


I really do not believe this is a bug, in the end, just inconsistent AI coupled with people (myself included) not noticing what was going into some enrichment feeders and just trusting the global feed price settings for the habitat.

Complete logs in spoilers.

Food Costs (Total)
y1: 10226.38 (no enrichment feeders)
y2: 17726.99 (no enrichment feeders, 4 offspring in TC)
y3: 15339.60 (no enrichment feeders, no new offspring, 4 in TC)(Turtle 1 enclosure food costs doubled for no reason)
y4: 22727.40 (no enrichment feeders, no new offspring, 4 in TC)(Lion 1 enclosure food costs doubled for no reason)
y5: 15226.80 (no enrichment feeders, no new offspring, 1 animal in TC, other 3 placed in nursery zoo at end of y4 (Baseline feed price for all 4 enclosures if no bug)
y6: 20026.80 (no enrichment feeders, 3 offspring in TC, grizzly 1 and 2 added for research)
y7: 27527.40 (no enrichment feeders, 1 offspring sent to TC)
y8: 20026.80 (no enrichment feeders, no change in pop. same costs as y6)(Added 2 Chief Beef beginning y9 for bug testing)
y9: 22426.80 (no enrichment feeders, no change in pop. price difference is due to Grizzly habitat bug)(Chief Beef shows no impact)
y10:22426.80 (no enrichment feeders, 3 offspring sent to TC)(Chief Beefs still shows no impact - removing)(Enrichment feeders added Jan y11)

adding enrichment feeders to lion1, turtle 1 and grizzly 1
y11:36966.57 (1 blood pumpkin, 1 frozen fruit, 1 forage feeder in test group.)
y12:21368.38 (no change in feeders)
y13:26306.97 (no change in feeders, cannot explain the Turtle numbers. Grizzly 1 and 2 prices have doubled)
y14:25952.97 (no change in feeders)
y15:29768.97 (no change in feeders)

changed enrichment in 1st set of exhibits. Added enrichment to control group, since base numbers are now established
y16: 22576.79. Enrichment feeders using grade 1 food seem to be less expensive than food tray base prices by 1 cent.
y17: 23626.79. No change in feeders. Keeper seems to have missed a feed in Lion1. Grizzly2 habitat price doubled.
y18: 25276.81. No change in feeders. Made changes to habitats in Jan. y.19. Grade 3 food, no enrichment for group2. Only fancy enrichment for group1.
y19: 35803.19. Theory: placing multiple enrichment feeders can lead to overfeeding, since some feeders seem to always get filled to max capacity (blood pumpkin in particular).Wanting to satisfy food enrichment needs seems the source of cost explosions, especially if player is unaware of food grade inside these items.
y20: 24116.98 Previous explanation doesn't seem to stick. Pumpkin and pinata stayed the same. Fruit as well. Turtle feeding behaviour seems odd. Keeper AI not being consistent? Grade 3 food confirmed.

I dont really get this. Nothing has changed. I improved my staff, but thats it...

6 ostriches don't cost 27k to feed no matter the unit
Well... they could.
IRL they eat about 2kg/day per bird, so for 6 birds it would bring the feeding cost to about 6 bucks per kilo....
What enrichment items do you have in there?

Edit: Are you sure about the 35 times? Have you checked the capacity and food grade of each enrichment item?

Edit 2: 4500 per bird does seem like a lot, since lions are about 2k5 per cat per year...

Edit 3: How much food is added to your habitat every time your keeper feeds it? If your 35 times is correct, should be about 5kg, and numbers check out...

(Sorry for the multiple edits, am at work)

Happened to me and my boyfriend as well. I had gharials and for reasons unknown the food cost went up from like 5k to 34k (actually now that I remember the food cost went up for all animals, but the gharials were the worst by far). I changed absolutely nothing. So I waited and monitored for a whole year and when the next year came the cost went back to normal. No idea how it happened and how it got fixed. My bf solved it by deleting staff gate and boxing all the animals and putting them into trade center.
 
I really dont understand this jump in my picture. I changed absolutely nothing.

Year 1 83k
Year 2 185k
Year 3 72k

What is this?
To see things clearly, you will need to pause the game in Jan each year and see the feeding costs for each habitat by clicking on them.
Be mindful that the habitat budget is split between fence repairs and food costs - you need to look at food costs...

As stated by Agathorn, keeper AI is inconsistent: some enclosures get fed twice sometimes, which can lead to pretty big spikes in the budget.

Any change in population will affect food costs, and if you are too slow in removing offspring when a feeding is coming up (if you have a nursery zoo, for instance), they will be counted in the food ration.

Also, be mindful of which enrichment items are in your habitat. Some hold grade 3 food regardless of your habitat’s setting, and you will be billed accordingly.
 
I have this problem aswell. The problem is definately with my lions in the main zoo. As soon I have around 5-6 lions in the habitat the costs go crazy. So what I do now is to keep 1 male and 1 female.. have them make babies.. and then contrapt the female. Cuz more then 4 lions will make you bankrupt. The donations just isnt far from enough to substain the food cost. I supose there should be loss as drink and food stores should make up for small losses... But not all my 25 stores combined can keep up the cost. Sad.. As lions are suposed to live in big packs. But that is not possible atm :p
 
Honestly I didn't read through everything but did see something odd today while I was playing. I haven't been loosing money so I haven't paid a lot of attention to what I've put out for food cost but looking at an exhibit that I have okapi and bongo in the food cost for these two animals is very different.

For okapi it is grade 1 $6.26, grade 2 $6.90 and grade 3 $7.38.
For bongo it is 1 $23.99, 2 $26.39 and 3 $29.15.

They would eat a very similar if not identical diet, why the huge difference in food prices? I don't know if it varies on the number of animals but I have two of each in the exhibit so it should be comparable.

What is this?
Like I said previously the "explosions" from my research appear to be from a keeper giving an extra feeding or two on year and not on another year. For example, when watching and logging my two bengal tiger habitats I found that some years they will get one feed, and other years they will get two feedings. That is a 100% swing in food prices for those habitats year to year depending on the feeding once or twice. Now scale that up to all habitats sometimes getting more or less feedings in a given year and you can see how the prices can change drastically year over year.

Sadly this will always be the case as long as we manage staff simply by "how often should some do this thing" rather than being able to schedule staff by saying "Do this in May, Aug, and October".

I'm actually tempted to try changing the keeper frequency in my habitats from the gospel 1 month to something like 6 months and see what happens. We all tend to use 1 month because we fear our keepers don't work properly and don't feed properly, but the truth is in watching my keepers the majority of the time they visit they dont' determine anything needs to be done. But the time they spend checking takes time out of their day. Thus some experimentation with longer frequencies I think is in order.

I have like 12 lions at my zoo in three different habitats, more when you include transient babies and I'm still making money.
 
My feeding bills are over 150k per year with no reason it should be happening. I've had no trouble making money up til this point, my zoo has been open for close to 100 years, I've routinely had around 300 animals. Suddenly, with very little changes, feed costs are so high I'm losing overall income. I'm down from 600k to 450k in a few hours of playing with no construction. I haven't been putting new shops, new bathrooms, new anything, I'm just paying out the nose for animals that aren't earning their keep.
 
That explains why my zoo got bankrupt, and I tought I was doing something wrong.
I am done with this game entirely, with all the bugs it has provided me with a lot more headaches and frustration than enjoyment, I am checking with steam for a refund
