Just so you know ZachyWacky my great grandparents bought batches of Leghorns and used them as dual purpose birds, they would replace the rooster they kept as necessary and keep a few pullets to replace the laying hens they culled... and the rest were raised for meat. The leghorns tasted yummy to me anyway, still better than what my parents would get at stores. So the idea of cross breeding Leghorns with Cornish Rocks I think might be a good idea...
