The RSPCA visited the Cairns North primary school to teach children about animal welfare through interactive stations, The Cairns Post reports. RSPCA Queensland's senior education officer Daryl Joy said students were able to test out a human-sized battery hen cage to highlight the confined spaces egg-laying hens often live in at poultry farms. "It's also a chance to learn about humane values and animal care in a fun-filled and challenging way," Mr Joy said. More at the Cairns Post.
