Admission to the Brookfield Zoo is free this Thursday, like every Tuesday and Thursday through February. But unlike any other time of year, this Thursday includes a free pass to break the zoo’s number one rule: You can feed the animals, at least domesticated ones like Moose the Nubian goat (not pictured), Mocha the llama, Whisper the miniature horse, and Heidi the reindeer. Feeding time’s 1 PM. For basic info, see the Reader’s listing for the Brookfield Zoo.
