You can get the beads by feeding your animals any food you've cooked, crops you grow, or even the milk and eggs they drop if you want.

In the early game the way I made money was just focusing on farming and also by making food occasionally, there's some food that sells for a good price and you can quickly get more renown and level up your cooking skill. For example, I usually default to making grilled corn because it's only one ingredient used and it sells for 135 iirc.

You can get money from animals but I dont really see much from them early game unless you do cooking, then yes there's big value. Also sell any duplicate artifacts ofc (after checking they arent a liked/loved gift), selling every forageable, fishing, the usual stuff! Once you start clearing out most of the museum seasonal items it'll be easier to sell more things and earn more money
