Mesorah
Why only birds with an established tradition are eaten as kosher today, even though most bird species are not on the forbidden list.
In 2004, the global kosher market experienced a sudden jolt over the ubiquitous Leghorn chicken. For decades, the white Leghorn had been the commercial gold standard for egg production in the United States and Israel.
In 2013, the Leghorn chicken was the subject of a kashrus controversy. In 2017, the Braekel chicken was the subject of another kashrus controversy.
A number of years ago, as Pesach approached, my daughter Sara Hindy noticed that there was a bird sitting on a nest in the tree right outside our front window.
