This is what I have done for the first part of the temporary farm, I added 3 level 4 winter fields, a level 3 stone mill, some houses and a few penguin pools. It cost 20,490,000 farm dollars and 14,836 gold.
After this, I will upgrade the fence, gate and the level 1 house in the left corner. I will then try to build a few more houses (due to the fact that the running costs of the farm will not go too high at the moment, it is acceptable to have a lower happiness temporarily for the moment) so we can build an extra few penguin pools and maybe the silo soon.
I would also recommend growing sardines in your winter fields to start producing penguin feed for your penguin pools so you can start collecting dung as soon as possible. Once you have enough feed, I would grow some flax to give to the workshop to complete the Chapter 1:1 task. I would not recommend taking the stone mill higher than level 3 since that will be able to produce feed fast enough for your penguin pools and the workers can be used in other buildings instead.
Resources spend after day 1:
37,990,000 farm dollars
