Brownsville, TX’s Gladys Porter Zoo’s Cassowary chicks are 5 months old now and they’ve grown a lot in that time. DNA testing determined there are 2 males and 1 female. They will soon outgrow their temporary pen outside of the building where they hatched.  An exhibit area next to the parents, Clementine and Irwin, is being baby-proofed so that staff can soon move them onto display for our public to enjoy.
