Heritage breed chickens are lower in linoleic acid than Cornish chickens due to slower growth and foraging.

“those are the chickens that I actually use most frequently in my home they were very lean they make amazing broth and literally in my home when I'm making my broth out of my heritage bird compared to making out of the Cornish bird I can smell the difference from upstairs because that heritage bird their bones are stronger even though our chicken our course is also fabulous I might use it a lot for roasting you know it's a different level of different complexity to it so it's almost like I didn't smell the difference in the diet there's more complexity as more richness there”
