The zoo doesn't have only animals, its open to do others activities too. But you still can see them
Depends on the weather, Presently it is cooler than normal in Chicago When it is cold as it is now. The majority of the animals are kept inside
Eduardo and Robert sum it up nicely.
They leave a few out to be viewed
A few animals are inside exhibit buildings therefore will open at 10am and you won't be able to see until then
May be in summer, it may open at 7, but we went after 10 during summer.
If they are out..
