The same simple economics that gave rise to their predominance will keep them in play. Leghorn breeds simply are more efficient at feed conversion on a commercial scale, giving little reason to develop a brown egg Leghorn.
I doubt they use 'leghorns' or any other pure beed these days.....the commercial hybrids are far more profitable.
