When I was in early middle school I would bring hatchery catalogs to school so I could read about different chicken breeds during free time. The catalogs would have a breed summary, pictures, the year is was admitted by the APA, the average weight, annual egg production, ect. One kid came up to me, looked at what I was reading, and said "it's like sport stats, but for chickens."
I do this in my college classes before the professor gets there
