How To Make The Most Money In Stardew Valley

Here's the math:

Stardrop Optimal Crop Calculation

Sheet1 Notes: 1) Assuming Tiller + Artisan profession. 2) Assuming that the plants are fully grown already (if they are a regenerating crop). 3) This does not account for the Jar/Keg time (e.g. Unlimited Kegs are assumed). 4) Speed-Gro will stay in the ground forever for the Island Farm / Greenh...

From this data, we can see that the optimal way to make money is as follows:
1) On the island farm + greenhouse, use all Hyper Speed-Gro + Starfruit. Keg all Starfruit. (There are 792 squares available on the island farm, which gives you 272,250g per day.)
2) On your normal farm, make as many Deluxe Sheds as possible and fill them with Golden Chickens. Mayo all Golden Eggs.
3) With the remaining squares on your normal farm, fill them with Ancient Fruit. Keg all Ancient Fruit.
4) In this setup you wouldn't want any sheds on your farm, since that wastes space. Put the kegs in the desert + southern forest + bus stop, etc.

Of course, this is all very hypothetical, because the game is essentially over once you unlock Golden Chickens - there's no point to farm further gold. Consider that to unlock Golden Chickens, you already have the infrastructure in place to get 10 million for the clock. So at this point you basically have unlimited gold already, and there's nothing more expensive to buy than the golden clock, so there's no point to improve upon your existing infrastructure.

The real point of the game in patch 1.5 (from a min-max perspective, anyway) is to get the Statue of True Perfection by 1 Spring on year 3.
(You are gated behind the recipe for Shrimp Cocktail on Winter 28, and you have to sleep once after getting Perfection, so the first possible day that you can get the statue is Spring 1.)
This is actually pretty trivial, so you would also want to tack on some arbitrary secondary goal, e.g. also collect every hat in the game.
Now that I think about it, maybe a better challenge would be to get max Perfection, minus the gated recipes, on the earliest possible date in Year 2 that you can. This would allow any intelligent optimization to actually pay off.

Edit - Is it confirmed that Golden Chickens *always* make 1 Golden Egg per day?
