In 1915, Hershey proclaimed itself the âlargest free private zoo in Pennsylvaniaâ and in 1916, the zoo was entirely remodeled and a large central building was added. The next major change to the zoo did not take place until the 1930s. The 1930s were a period of growth and expansion for the Hershey Zoo. By the end of the decade the zoo covered forty acres and contained individual houses for primates, carnivores, small mammals, antelopes, tropical birds, pheasants, and fish as well as outdoor cages and enclosures.
