Oh, that is not good news at all. Eggs cost 50G and Oliver had been hoping that, if a chicken cost 800G, he was learning something about investments that paid back 100% of their cost in 16 days, which would've made it a lot more likely that he wouldn't starve. But that logic doesn't work at all if chickens eat a Grass per day and each of Grass costs 50G if you buy from Marnie. Turning eggs into chickens takes an Incubator, and he doesn't know the reselling price of those...
"Thanks. Possibly a much stranger question--how can I find out how many G I have, or how do other people know how much G I have?" Going straight to what is the metaphysical nature of G might get funny looks, Oliver figures.
