Artificial Chicken Intelligence

A certain doctor created the perfect Frankey (incubator chicken).
It was the ultimate breed of broiler chicken.
This was because it was a breed equipped with a super biological AI called 'Artificial Chicken Intelligence' inside its brain, capable of managing growth speed and growth volume at maximum capacity.
This breed was not just a one-generation chicken, but a super chicken programmed to properly produce offspring that also possessed Artificial Chicken Intelligence, allowing for the almost permanent production of high-quality broiler chickens.

Broiler chicken farmers, whose harvest yields depend on growth differences, flocked to buy Frankeys.
After all, stable income is one form of peace of mind for humans.
But the doctor's prediction was wrong.
Most of the many Frankeys raised were excellent, but some were no different from old-fashioned chickens and did not produce stable meat.
Even after changing everything for the Frankeys—the coops, the feed—a certain percentage of Frankeys still wouldn't grow.
The doctor was given a strange nickname, something like 'Doctor Air-Theory'.
But I wonder if anyone ever thought that there is no such thing as a perfect living creature.
It should be common knowledge that even if you change the brain, individuals whose bodies cannot keep up will be left behind, as the body shares information beyond just the brain.
Why would the doctor, of all people, not understand such a simple thing and create the Frankey?
If he hadn't created them, chickens wouldn't have increased so much and reigned as the primary inhabitants of the Earth.

Well, I'm not human so I don't know, and the corn tea is delicious today, so that's fine.

The scientist-like chicken wrote this in his diary and brought the fragrant corn tea to his beak.
His job is to think and explore, but taking a break from writing and research to have corn tea was his daily routine.
He thinks while watching the chickens living peacefully.

Whether individualistic chickens change the population into a chicken-led one, the Earth keeps turning today, so it is peaceful.
Isn't that just fine?

Afterword
Long time no see, it's Mouosote.
I wrote a short story on a whim and with momentum for the first time in a while.
I guess it's maybe sci-fi?
It's not great, but I'd be grateful and thrilled if you read it, and comments would make me happy.
