if memory serves they eat 2 food per day.

they eat all foods equally, typically preferring the one the wellbeing bar is the lowest for.

the major exception are berries, they only eat berries if there is no other choice available. berries also don't give wellbeing, so folktails can pretty much ignore them entirely.

So, if i have for example 4 types of food, i only need 0,5/day and beaver to produce? And they do not for example demand more bread than potatoes?

Looking at the wiki (assuming it's still correct), it's 2.67 units of food per day, so a little higher, but you weren't far off with 2.

Also note each food type has the same food value, i.e. 1 carrot is equal to 1 maple pastry for food value, although the well being bonus does differ (zero (berries) 1, 2 or 3 bonus depending on food type).

As such for an even spread, just produce and store the same amount for all types you make.

I typically just build a medium warehouse for each type, and add a new warehouse as I start producing each new type of food. i.e. Berries first, then carrots etc etc.

For ref, each faction has 9 food types in total, so plan for 9 medium warehouses. I typically just plan for a 3 x 3 stack of medium warehouses somewhere near my town centre (Iron teeth also has coffee, but that goes in a liquid tank). That gives you 1,800 in food (or 1,600 if you ignore the berries).

In my experience, you don't really need to store any more than this (unless having more than one separate 'town centre'), as it's only really a buffer and central store, but you can use the stored amounts as a visual guide to know if anything is being under produced, and bump up production for that specific food type if it's not filling up the warehouse (which 9 out of 10 times is just adding more farming for the raw item).

I do not build arround my towncenter. Maybe if i can move it. But my houses are 40 tiles away from the town center. And so my food storages are integrated in the houseblocks. 400 of each food and 600 Water can i storage per block of 243 Beavers. I have 4 of these blocks arround my towncenter.
The Center is not used after the food in it is empty. And because of the 4 Worker... i have currently 52 Workers with the towncenter.

I replaced all buildings away because the area arround the towncenter is perfect foodland and i will not block it. And so with LOTS (im nean REALLY LOOOTTTSSS!!) Dynamite and dry i build huge flat areas and a huge water reservior. If you see the original map and my map you will not recognize it. I like it flat and so i made it flat.

I think 2,67 is the iron teeth... the folktrails are lesser. But i plan with reserve...
So i need 3 / 9 = 0,33 x 1.000 = 330 food per day per source. Now i will ask my excel how much tiles and buildings per food i need. :-)

And because i customized my game and play with arround 1.000 beavers my storages are huge. I must, because i have 60 days dry and bad tide. And my storage is planed to survive 150 days without plants and water.
Because if my reservour gets contaminated by a mistake i have a huge problem. I must emptey it and fill it new. And my exit is not so big i would wish. Also i must canalize all fresh water to the reserviour because the current one needs 54 days to fill it up without breaks.

My plan is with the next update to overbuild the whole thing and transfer my beavers over the watercave. So i will have a huge mountain with 1/3rd of the map which is empty and filled with water in its core and on the top my beavers. And 3 waterfalls from aquaducts go inside, some holes for the pumps and at the side my overflow-waterfall.
And if i calculated correct in the mountrain will be 36M Squaretiles of water if full.

I like building huge. I would build bigger if the game would not have the cap of 1,1k beavers and massive performance problems with this.

Another question:
You said they need 1 book per day and beaver...

I plan to have arround 1.000 beaver. Does this mean i must produce 1.000 books a day?

I mean this are 16h work, 1,6h/book = 10 books per day, so i need 100 Buildings? Thats insane. I also need paper to work and wood. That are 500 wood per day!

I mean who desided that books need a 1:10 ratio? Water has a 12:1 ratio but need no ressources. Food has a arround 1:15 ratio but also produces from nothing. And books who need energy, paper und wood this? I would understand a 1:20... but 1:10?
And i need 5 Worker for the buildings, no for energy in midgame but 2 cutters i think. So i need 7 beavers to have books for 20 beavers. Thats insane...

are you taking the wellbeing workspeed buff into consideration? you can slap at least 50% on by the time you get around to making books.

i usually don't bother with books, so i don't really know how fast the satisfaction decay is.

but 1000 beavers is a very large settlement so yeah i imagine you will need multiple of pretty much all buildings with a loooot of trees to support it.

no not really, because wellbeing is currently not an option. Its easier to build up a base of for example 300 beavers and than build up the wellbeeings for 1.000 beavers than building it up constant or trying to build up the nessessary food from very early.

Beavers choose a food based on what is the lowest (and available) in their well being food category.

then don't worry about books. do the easy wellbeing things first and maybe start thinking about books when it's above 30.

My intention was, that i am building up my industry currently from manpower to wind and water-power with batteries. And for the capacity and placements in the area it would be good to know how much books i need to produce.
