I know they didn't all repeat the behavior, but it really is instinctual, so not a fluke.
My last batch of chicks at 15 days old were reliably returning to their brooder (with full run access during the day) at sunset, because that's where their heat source is. At 29 days old they homed themselves to the adult coop only 2 days after being locked out of the brooder (of course part of that is they're following the adults, but still, that was much faster than I anticipated!)
