The OP there also has a pretty bad riddle (due to a grammatical error that completely changes the meaning and makes the intended solution nonsensical, and a solution that many people wouldn’t even have heard of).

I think maybe the original poster is making some sort of additional assumption that the farmer must be selling chickens as meat at the market and a chick wouldn't be sold for that purpose until it's a mature chicken?
(Of course depending on how you interpret the question a chick is a chicken (species) and there's nothing inherently preventing reselling the chicks so I don't really understand why OP thinks the ai answer is clearly objectively wrong. It seems more like a matter of interpretation.)
Anyways this thread is a perfect example of the chaotic datasets that are being used to train FMs. These arguments of whether it’s reasonable to assume a chick could mature into a chicken within a week are happening everyday and have been taking place for years. Safe to say a billion dollars has been spent on datasets to train FMs where everybody has a different interpretation and the datasets are not aligned.
